NAME
explain_select_or_die - blah blah and report errorsSYNOPSIS
#include <libexplain/select.h>void explain_select_or_die(int nfds, fd_set *readfds, fd_set *writefds, fd_set *exceptfds, struct timeval *timeout);
DESCRIPTION
The explain_select_or_die function is used to call the select(2) system call. On failure an explanation will be printed to stderr, obtained from explain_select(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:
explain_select_or_die(nfds, readfds, writefds, exceptfds, timeout);
- nfds
- The nfds, exactly as to be passed to the select(2) system call.
- readfds
- The readfds, exactly as to be passed to the select(2) system call.
- writefds
- The writefds, exactly as to be passed to the select(2) system call.
- exceptfds
- The exceptfds, exactly as to be passed to the select(2) system call.
- timeout
- The timeout, exactly as to be passed to the select(2) system call.
- Returns:
- This function only returns on success. On failure, prints an explanation and exits.
