<strong>PERROR</strong>
==SYNOPSIS==
#include <stdio.h>
void perror(char * s)
==DESCRIPTION==
This routine will print on the stderr stream the argument s, followed by a descriptive message detailing the
last error returned from an open, close read or write
call. Unfortunately CP/M does not provide definitive
information relating to the error, except in the case
of a random read or write. Thus this routine is of limited usefulness under CP/M. MS-DOS provides much more
information however, and use of <strong>perror</strong>() after MS-DOS
file handling calls will certainly give useful diagnostics.
