Usage
#include <libexplain/tcsetattr.h>
void explain_tcsetattr_or_die(int fildes, int options, const struct termios *data);
int explain_tcsetattr_on_error(int fildes, int options, const struct termios *data);
Overview
The explain_tcsetattr_or_die function is used to call the tcsetattr(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_tcsetattr(3) function, and then the process terminates by calling exit(EXIT_FAILURE).
The explain_tcsetattr_on_error function is used to call the tcsetattr(3) system call. On failure an explanation will be printed to stderr, obtained from the explain_tcsetattr(3) function, but still returns to the caller.
