SYNOPSIS

       char *explain_strdup_on_error(const char *data);

DESCRIPTION

       The  explain_strdup_or_die  function is used to call the strdup(3) system call. On failure an explanation
       will be printed to stderr, obtained from the explain_strdup(3) function, and then the process  terminates
       by calling exit(EXIT_FAILURE).

       The explain_strdup_on_error function is used to call the strdup(3) system call. On failure an explanation
       will be printed to stderr, obtained from the explain_strdup(3) function, but still returns to the caller.

       data    The data, exactly as to be passed to the strdup(3) system call.

RETURN VALUE

       The  explain_strdup_or_die  function  only  returns  on  success,  see strdup(3) for more information. On
       failure, prints an explanation and exits, it does not return.

       call.
