explain_select_or_die − blah blah and report errors
#include <libexplain/select.h>
void explain_select_or_die(int nfds, fd_set *readfds, fd_set *writefds, fd_set *exceptfds, struct timeval *timeout);
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.
blah blah
explain select(2) errors
terminate the calling process |
