Generally, it also costs less to process an ACH transfer than a credit card payment or wire transfer. While ACH payments and wire transfers are both ways to move money between two accounts, there are a number of differences between them.
Wire transfers are processed in real time, as opposed to ACH payments, which are processed in batches three times a day. As a result, wire transfer funds are guaranteed to arrive on the same day, while ACH funds can take several days to process.
Wire transfers are also more expensive than ACH payments. They both describe the same payments mechanism. There are two types of ACH payments.
Here are two examples of how they function in the wild. Many companies offer direct deposit payroll. Employees need to provide a voided check or a checking account and routing number to set this up.
Consumers who pay a business say, their insurance provider or mortgage lender at certain intervals may choose to sign up for recurring payments. Aside from the Automated Clearing House network which connects all the banks in the United States , there are three other players involved in ACH payments:.
When you sign up for autopay with your phone company, you provide your checking account information routing and account number and sign a recurring payment authorization. The two banks then communicate to ensure that there are enough funds in your bank account to process the transaction. ACH payments typically take several business days the days on which banks are open to go through. The ACH network processes payments in batches as opposed to wire transfers, which are processed in real time.
Per the guidelines set forth by NACHA , financial institutions can choose to have ACH credits processed and delivered either within a business day or in one to two days. ACH debit transactions, on the other hand, must be processed by the next business day. After receiving the transfer, the other bank might also detain the transferred funds for a holding period. The changes which are occurring in phases will make possible widespread use of same-day ACH payments by March ACH payments are typically more affordable for businesses to process than credit cards.
Others charge a flat percentage fee, ranging from 0. Providers may also charge an additional monthly fee for ACH payments, which can vary. Here are the four most common reject codes:. It also provides a collaboration feature that allows multiple family members to take turns editing the same file AC file.
You can only open AC files with Ancestral Quest. The FileInfo. If you would like to suggest any additions or updates to this page, please let us know. AC File Extension. AC File Extension 3 file types use the. Autoconf Script 2. Ancestral Quest Collaborative Database File. The standard way is to generate a config. The process is similar to, but not identical to creating a makefile. The relevant part of configure. This isn't a rigid rule. Sometimes the clearest, simplest and most elegant solution to some gnarly cross-platform portability problem involves the preprocessor.
In most cases though however, the cleanest portable designs will rely on separating off platform specific parts into different modules and files.
Regarding point 4, you should really avoid having a public config. When you can't keep the dependencies on it as small as possible, by putting anything not required to be public in a private config. Autoconf allows you to specify a whole list of headers.
So if you've made it this far, you probably noticed that debugging and checking the scripts was a bit of a pain, because you had to edit them to make one of the tests fail then rerun autoconf, then put it back again. Autoconf provides two methods of configuration.
They are almost identical in function, but the conventions are:. That means you can also supply arguments to with. Both styles simply set an environment variable. You can then act on that with the usual shell scripting. The second argument is the text which appears if. Much like the other tests, you can also specify actions for if the commandline argument is present or absent. This example is very similar to Example 6 , except that the relevant part of configure.
Now, if --without-zlib is specified then it doesn't even try to run the tests, and carries on as if the tests have failed. Out of tree builds are one of those features that are rarely used, but probably ought to be used more. They're kind of handy because with the same source tree, you can build various versions standard, debugging, cross compiled from a single source tree, without having to keep multiple copies in sync. It's also so easy to do that you may as well do it.
Autoconf supports it by providing srcdir which tells you the directory of the configure script and of course by extension the source code. That's it as far as autoconf goes, it's completely automatic. You then need to use the virtual path vpath feature of make. Essentially, add the line. That's all there is to is. Go into example 9 and run autoconf to create the configure script. It should work just as well as if you ran configure and make from within the source directory.
At this point you now have a basic, but fully featured autoconf build system. Most of what to do can probably be accomplished with what you've covered so far, however you may come across things which aren't covered.
If you do get into writing your own tests, then it's a very good idea to build off the autoconf macros if at all possible. I know from experience that it's an especially bad idea to write tests that probe the machine you're running the autoconf script from because then you won't be able to deploy the resulting program on a different mahchine for example if you're cross compiling.
Even without machine specific tests, there are other things you might want to look for or other parts of the build system you might want to probe. There are several levels of debugging which you need to do.
There's debugging your shell code I'm not going to help there , debugging tests in the configure script and debugging the generated files. If you're debugging autoconf tests, the best place to look is config.
That stores lots of useful information about tests that fail, including the compiler line with all flags and the bit of code being compiled. It's often quite large, so you'll have to search through it. You can also put your own text in the log to aid that process. Assuming your configure script runs correctly, the next layer of the stack with bugs is the generated Makefile and config. It would be awfully tedious if you had to re-run configure every time you changed one of those. Fortunately you don't.
Before autoconf completes, it generates a script called config. This script stores the results of autoconf and does the template substitutions on the. So, if you edit your Makefile. There's also a stack of languages so you can push and pop them to make temporary changes.
At this point I'm just going to list a selection of what's available. The usage should be reasonably obvious from the names. For quite a lot of common cases, there are more specialised macros to help. Note again, this is a small selection to give a flavour. Since this is a tutorial I can't cover them all, so it's best to browse the manual at this point. Autoconf provides good underlying tools, but doesn't provide tests for everything.
In many cases, instead of writing your own you can instead grab one already written from the huge official archive of macros. They're also very easy to use precisely because M4 is a macro language. First get this extension macro and put it in the m4 subdirectory.
Then use it in the following way:. The official extension macros are generally very well tested and so it's better to use those than roll your own. Sooner or later, you'll probably find that there's not a test for something you want to do repeatedly. For example, I like to routinely add flags to do with warnings, GDB symbols and so on. Here's an example of a custom test and its use. If you run the configure script it will attempt to add a whole bunch of flags to the compiler, but it won't cause errors if any of those flags are invalid.
