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