NAME¶explain_getchar_or_die - input of characters and report errors
DESCRIPTION¶The explain_getchar_or_die function is used to call the getchar(3) system call. On failure an explanation will be printed to stderr, obtained from explain_getchar(3), and then the process terminates by calling exit(EXIT_FAILURE).
This function is intended to be used in a fashion similar to the following example:
int c = explain_getchar_or_die();
- This function only returns on success. On failure, prints an explanation and exits.
