creating a file in the same directory as the executable program

I'm creating/reading/writing a file in my program, but initially the file will have to be created before it is used.

Do I create a file with fopen? If not, what function do I use?

Also, what directory path do I specify if I want to create the file in the same folder as the .exe file of the program that is creating the file?

Thank you.

Which OS/Compiler are you using?

Win XP/ Dev-C++

Yes, fopen() for write will create the file.

This code should work for you. It will create the file MyFile.ext in the same directory as your executable. Make sure and include <windows.h>. Another option is to use the executable path given to your main() or WinMain() function.

Code:

---

char buff[MAX_PATH], *p;
FILE *f;
GetModuleFilePath(NULL,buff,MAX_PATH);
p = strrchr(buff, '\\');
if(p)
{
  strcpy(p+1,"MyFile.ext");
}
f = fopen(buff,"w");

Just call fopen with the file name and the "w" parameter and it will create/overwrite a file in the executable's directory...

is there anyway to do this without using the WinAPI? How can I get the directory through standard command-based C?

No, it will create the file in the current working directory which could be different than the executable's directory.

Yes. Use the directory passed to main(argc, argv).

I think you're using MS Visual C++ too much...
