NAME explain_strndup_or_die - duplicate a string and report errors
SYNOPSIS #include <libexplain/strndup.h> char *explain_strndup_or_die(const char *data, size_t data_size); char *explain_strndup_on_error(const char *data, size_t data_size);
DESCRIPTION The explain_strndup_or_die function is used to call the strndup(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_strndup(3) function, and then the process terminates by calling exit(EXIT_FAILURE). The explain_strndup_on_error function is used to call the strndup(3) system call. On fail‐ ure an explanation will be printed to stderr, obtained from the explain_strndup(3) func‐ tion, but still returns to the caller. data The data, exactly as to be passed to the strndup(3) system call. data_size The data_size, exactly as to be passed to the strndup(3) system call.
RETURN VALUE The explain_strndup_or_die function only returns on success, see strndup(3) for more information. On failure, prints an explanation and exits, it does not return. The explain_strndup_on_error function always returns the value return by the wrapped strndup(3) system call.
EXAMPLE The explain_strndup_or_die function is intended to be used in a fashion similar to the following example: char *result = explain_strndup_or_die(data, data_size);
