io_createfile (3)

#include <io.h>

int io_createfile(int64* d,const char* s);

io_createfile sets d to the number of a new descriptor writing to the disk file named s, and returns 1. If s already existed, it is truncated to length 0; otherwise, it is created, with mode 0600.

If something goes wrong, io_createfile sets errno to indicate the error, and returns 0; it does not create a new descriptor, and it does not touch d. (However, it may have truncated or created the file.)
