io_readwritefile(3)	   Library Functions Manual	   io_readwritefile(3)

NAME
       io_readfile - open a file for reading and writing

SYNTAX
       #include	<libowfat/io.h>

       int io_readwritefile(int64* d,const char* filename);

DESCRIPTION
       io_readwritefile	 sets d	to the number of a new descriptor reading from
       and writing to the disk file named filename, and	returns	1.   The  file
       needs to	exist.

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