explain_wait_or_die − wait for process to change state and report errors
#include <libexplain/wait.h>
void explain_wait_or_die(int *status);
The explain_wait_or_die function is used to call the wait(2) system call. On failure an explanation will be printed to stderr, obtained from explain_wait(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_wait_or_die(status);
status |
The status, exactly as to be passed to the wait(2) system call. |
Returns:
This function only returns on success. On failure, prints an explanation and exits.
wait for process to change state |
explain wait(2) errors
terminate the calling process |
