Standard C Library Functions                           perror(3C)

NAME

perror, errno - print system error messages

SYNOPSIS

#include <stdio.h> void perror(const char *s); #include <errno.h> int errno;

DESCRIPTION

The perror() function produces a message on the standard error output (file descriptor 2) describing the last error encountered during a call to a system or library function. The argument string s is printed, followed by a colon and a blank, followed by the message and a NEWLINE character. If s is a null pointer or points to a null string, the colon is not printed. The argument string should include the name of the program that incurred the error. The error number is taken from the external variable errno, which is set when errors occur but not cleared when non-erroneous calls are made. See intro(2).

USAGE

If the application is linked with -lintl, then messages printed from this function are in the native language speci- fied by the LC_MESSAGES locale category. See setlocale(3C).
