System Functions (s and S) spt_waitpid(2)
NAME
spt_waitpid - Initiates thread-aware waitpid( ) function
LIBRARY
G-series native OSS processes: /G/system/sysnn/zsptsrl
H-series OSS processes: /G/system/zdllnnn/zsptdll
SYNOPSIS
#include <spthread.h>
pid_t spt_waitpid(
pid_t pid,
int *stat_loc,
int options);
PARAMETERS
See the waitpid(2) reference page.
DESCRIPTION
This is a thread-aware version of the waitpid() function. The socket must be nonblocking for
this function to be thread-aware.
The following macro maps spt_waitpid() to waitpid( ) and has been defined in spthread.h:
#define waitpid(pid, stat_loc, options) \
spt_waitpid(pid, stat_loc, options)
This macro is available only when SPT_THREAD_AWARE has been defined before including
spthread.h, as follows:
#define SPT_THREAD_AWARE
RETURN VALUES
See the waitpid(2) reference page. Also, if a signal is received via the pthread_kill() function
and is not blocked, ignored, or handled, -1 is returned with an errno value of [EINTR].
STANDARDS CONFORMANCE
This function is an extension to the XPG4 Version 2 specification. Interfaces documented on this
reference page conform to the following industry standards:
• IEEE Std 1003.1c-1995, POSIX System Application Program Interface
The use of the header file spthread.h is an HP exception to the POSIX standard.
