System Functions (n - p) pthread_attr_getschedpolicy(2)
NAME
pthread_attr_getschedpolicy - Obtains the scheduling policy 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_getschedpolicy(
const pthread_attr_t *attr,
int *policy);
PARAMETERS
attr Specifies the address of the thread attributes object whose scheduling policy
attribute is obtained.
policy Receives the value of the scheduling policy attribute.
DESCRIPTION
This function obtains the value of the scheduling policy attribute of the thread attributes object
specified by the attr parameter and returns it in the policy parameter. The scheduling policy attri-
bute defines the scheduling policy for threads created using this threads attributes object.
See the pthread_attr_setschedpolicy(2) reference page either online or in the Open System Ser-
vices System Calls Reference Manual for information about the scheduling policy 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.
