NAME

strerror − get error message string

SYNOPSIS

#include <string.h>

char ∗strerror(int errnum);

DESCRIPTION

strerror() maps the error number in errnum to an error message string, and returns a pointer to that string.  strerror() uses the same set of error messages as perror().  The returned string should not be overwritten. 

ERRORS

strerror returns NULL if errnum is out-of-range. 

SEE ALSO

gettext(3I), perror(3C), setlocale(3C)

NOTES

If the application is linked with −lintl, then messages returned from this function are in the native language specified by the LC_MESSAGES locale category; see setlocale(3C).
