System Functions (n - p) pthread_attr_getinheritsched(2)
NAME
pthread_attr_getinheritsched - Obtains the inherit scheduling attribute of a thread attributes
object
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_attr_getinheritsched(
const pthread_attr_t *attr,
int *inheritsched);
PARAMETERS
attr Specifies the address of the thread attributes object whose inherit scheduling
attribute is obtained.
inheritsched Receives the value of the inherit scheduling attribute.
DESCRIPTION
This function obtains the value of the inherit scheduling attribute of the thread attributes object
specified by the attr parameter and returns it in the inheritsched parameter. The inherit schedul-
ing attribute specifies whether threads created using the specified threads attributes object inherit
the scheduling attributes of the creating thread or use the scheduling attributes stored in the
threads attributes object specified by the pthread_create() attr parameter.
See the pthread_attr_setinheritsched(2) reference page either online or in the Open System
Services System Calls Reference Manual for information about the inherit scheduling attribute.
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
H06.21/J06.10 or later RVUs.
