ELF_ERRMSG(3)             Libelf Programmer's Manual             ELF_ERRMSG(3)



NAME
       elf_errmsg - return the error message string for a given libelf error
       code.


SYNOPSIS
       #include <libelf.h>

       const char *elf_errmsg(int err);


DESCRIPTION
       The elf_errmsg function retrieves a human-readable string corresponding
       to the most recent error code set by a libelf library function. If err
       is 0, the function returns the error message for the most recent error
       code. If err is non-zero, the function returns the error message for
       the specified error code.


PARAMETERS
       err    An int value specifying the error code. If this value is 0, the
              function returns the error message for the most recent error or
              NULL if none occurred. If this value is -1, the behaviour is
              similar to the previous case except that a legal string will be
              returned instead of NULL.


RETURN VALUE
       The elf_errmsg function returns a string containing the error message.
       If there is no corresponding error message, it returns NULL.
