SYSERRLST(3)						     Library Functions Manual						      SYSERRLST(3)

NAME
       syserrlst, __errlst - read system error messages from file

SYNOPSIS
       char *
       syserrlst(err)
       int err;

       char *
       __errlst(err, path);
       int err;
       char *path;

DESCRIPTION
       Syserrlst(3) reads the error message string corresponding to err from the file /etc/syserrlst.

       __errlst(3)  reads  the	error  message	string	corresponding to err from the file path.  The file path must be in the format described in
       syserrlst(5).

       NULL is returned if err is out of bounds (negative or greater than the highest message number in /etc/syserrlst or path) or  if	the  error
       message file can not be opened.	It is the responsibility of the caller (strerror(3)) to check for and properly handle the NULL return.

RETURN VALUE
       NULL  if  an error was encountered in opening the error message file, if the error was out of bounds, or if the file did not start with the
       correct magic number.  Otherwise a char * is returned pointing to a static buffer containing the text of the error message.

ERRORS
       syserrlst(3) and __errlst(3) can return any of the errors for the open(2), lseek(2), or read(2) system calls.

SEE ALSO
       perror(3), strerror(3), syserrlst(5)

HISTORY
       syserrlst(3), and __errlst(3) were created for 2.11BSD with the aim of saving 2kb of Data space in programs which called perror(3), or str-
       error(3).

BUGS
       The information is stored in a static buffer.
