Remove Multiple Files in a Directory

[CJason]

Is there a way to delete multiple files in a directory from C? I know there is the "remove" function...but, I think that is only to remove a single file, correct? What I'm looking for is something like "remove(*.dat)". Is that possible? If not, does someone have a simple algorithm that maybe loops though the *.dat files in a directory, and "removes" each one...one by one?

Thanks in advance!

No system independent library function(s) to scan directory in C, but there is such API in every system. Collect file names by "*.dat" template with this API (of your target system) then make loop with remove() function...

Apropos, you may use system("delete *.dat") call (correct cmd text for your target system too.

What OS are you running this on? Some possibilities are MS Windows has

remove()

with multiple ways of moving through directories.

Unix has

remove()
opendir()
readdir()
unlink()

that can be used in conjunction with each other. I think the remove() function is ANSI standard, it's definetly K&R standard. Or as already mentioned use system() to call the command line (possibly a script that does the work). If you don't want to use a script then you will have to use some form of loop to cycle through the files one at a time, looking for the .dat extension and deleting.
