#include <dos.h> unsigned int _dos_creat(const char *filename, unsigned short attr, int *handle);
This is a direct connection to the MS-DOS creat function call (%ah = 0x3C). This function creates the given file with the given attribute and puts file handle into handle if creating is successful. If the file already exists it truncates the file to zero length. Meaning of attr parameter is the following:
_A_NORMAL (0x00)
_A_RDONLY (0x01)
_A_HIDDEN (0x02)
_A_SYSTEM (0x04)
_A_ARCH (0x20)
See section _dos_open. See section _dos_creatnew. See section _dos_read. See section _dos_write. See section _dos_close
This function does not support long filenames, even on systems where the LFN API (see section _use_lfn) is available. For LFN-aware functions with similar functionality see section _creat, and section _creatnew. Also see section creat, and section open, which are Posix-standard.
Returns 0 if successful or DOS error code on error (and sets errno)

int handle; if ( !_dos_creat("FOO.DAT", _A_ARCH, &handle) ) puts("Creating was successful !");
