# io\_createfile(3)

create a file

## NAME

io\_createfile - create a file

## SYNTAX

**#include \<libowfat/io.h\>**

int **io\_createfile**(int64\* d,const char\* s);

## DESCRIPTION

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.)
