NAME
       elf_errmsg, elf_errno - error handling

SYNOPSIS
       [flag... ] file...  [library] ...

DESCRIPTION
       If  an  ELF  library  function  fails, a program may call to retrieve the library's internal error number.  As a side effect, this function
       resets the internal error number to zero, which indicates no error.

       takes an error number, err, and returns a null-terminated error message (with no trailing new-line) that describes the problem.	A zero err
       retrieves  a  message  for  the most recent error.  If no error has occurred, the return value is a null pointer (not a pointer to the null
       string).  Using err of -1 also retrieves the most recent error, except it guarantees a non-null	return	value,	even  when  no	error  has
       occurred.   If  no message is available for the given number, returns a pointer to an appropriate message.  This function does not have the
       side effect of clearing the internal error number.

EXAMPLES
       The following fragment clears the internal error number and checks it later for errors.	Unless an error occurs after the first call to the
       next call will return zero.

			 (void)elf_errno();
			 while (more_to_do)
			 {
				 /* processing ... */
				 if ((err = elf_errno()) != 0)
				 {
					 msg = elf_errmsg(err);
					 /* print msg */
				 }
			 }
