pthread_getschedparam - Obtains the current scheduling policy and scheduling parameters of a thread.
DECthreads POSIX 1003.1c Library (libpthread.so)
struct sched_param *param);
Interfaces documented on this reference page conform to industry standards as follows:
IEEE Std 1003.1c-1995, POSIX System Application Program Interface
Thread whose scheduling policy and parameters are obtained. Receives the value of the scheduling policy for the thread specified in thread. Refer to the description of the pthread_setschedparam(3) routine for valid parameters and their values. Receives the value of the scheduling parameters for the thread specified in thread. Refer to the description of the pthread_setschedparam(3) routine for valid values.
This routine obtains both the current scheduling policy and associated scheduling parameters of the thread specified by the thread argument.
The priority value returned in the param structure is the value specified in the attr argument passed to pthread_create(3) or by the most recent call to pthread_setschedparam(3) that affects the target thread.
This routine differs from pthread_attr_getschedpolicy(3) and pthread_attr_getschedparam(3), in that those routines get the scheduling policy and parameter attributes that are used to establish the priority and scheduling policy of a new thread when it is created. This routine, however, obtains the scheduling policy and parameters of an existing thread.
If an error condition occurs, this routine returns an integer value indicating the type of error. Possible return values are as follows: Successful completion. The value specified by thread does not refer to an existing thread.
Functions: pthread_attr_getschedparam(3), pthread_attr_getschedpolicy(3), pthread_create(3), pthread_self(3), pthread_setschedparam(3)
