23 strerror -- map an error number to an error message string
29 char *strerror (int errnum)
33 Returns a pointer to a string containing an error message, the
34 contents of which are implementation defined. The implementation
35 shall behave as if no library function calls strerror. The string
36 pointed to shall not be modified by the caller and is only guaranteed
37 to be valid until a subsequent call to strerror.
41 Requires that the system have sys_errlist and sys_nerr.
48 extern char *sys_errlist[];
54 return (((code < 0) || (code >= sys_nerr))
59 #endif /* HAVE_STRERROR */
61 /* end of strerror.c */
