io_readfile - Man Page

open a file for reading


#include <io.h>

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


io_readfile sets d to the number of a new descriptor reading from the disk file named s, and returns 1.

If something goes wrong, io_readfile sets errno to indicate the error, and returns 0; it does not create a new descriptor, and it does not touch d.
