System Functions (n - p) pthread_get_expiration_np(2)
NAME
pthread_get_expiration_np - Calculates an absolute expiration time
LIBRARY
G-series native OSS processes: /G/system/sysnn/zsptsrl
32-bit H-series and J-series OSS processes that use the POSIX User Thread Model library:
/G/system/zdllnnn/zputdll
64-bit H-series and J-series OSS processes that use the POSIX User Thread Model library:
/G/system/zdllnnn/yputdll
H-series and J-series OSS processes that use the Standard POSIX Threads library:
/G/system/zdllnnn/zsptdll
SYNOPSIS
#include <pthread.h> | #include <spthread.h>
/* pthread.h is required to use POSIX User Thread Model library */
/* spthread.h is required to use Standard POSIX Threads library */
int pthread_get_expiration_np(
const struct timespec *delta,
struct timespec *abstime);
PARAMETERS
delta Specifies the number of seconds and nanoseconds to add to the current system
time to determine an expiration time.
abstime Receives the calculated absolute expiration time. The resulting abstime value is
in Universal Coordinated Time (UTC).
DESCRIPTION
This function adds a specified interval to the current absolute system time and returns a new
absolute time, which is used as the expiration time in a call to the pthread_cond_timedwait()
function.
The timespec structure contains the following two fields:
tv_sec Is an integral number of seconds.
tv_nsec Is an integral number of nanoseconds.
On systems running H06.21 or later H-series RVUs or J06.10 or later J-series RVUs, you can use
either the POSIX User Thread Model library or the Standard POSIX Threads library for threaded
applications.
To use this function in a threaded application that uses the POSIX User Thread Model library on
systems running H06.21 or later RVUs or J06.10 or later RVUs, you must perform all of the fol-
lowing tasks:
• Include the pthread.h header file in the application.
• Compile the application using the _PUT_MODEL_ feature test macro or equivalent
compiler command option.
• Link the application to the zputdll library (/G/system/zdllnnn/zputdll).
On systems running H06.24 or later H-series RVUs or J06.13 or later J-series RVUs, you can use
the POSIX User Thread Model library with 32-bit or 64-bit threaded applications.
To use this function in a 32-bit threaded application that uses the POSIX User Thread Model
library on systems running H06.24 or later RVUs or J06.13 or later RVUs, perform the same
tasks (described above) used to enable the POSIX User Thread Model library on systems running
