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.
