pthread_attr_getschedparam(3C)											    pthread_attr_getschedparam(3C)

NAME

       pthread_attr_getschedparam, pthread_attr_setschedparam - get or set schedparam attribute

SYNOPSIS

       cc -mt [ flag... ] file... -lpthread [ library... ]
       #include <pthread.h>

       int pthread_attr_getschedparam(const pthread_attr_t *restrict attr, struct sched_param *restrict param);

       int pthread_attr_setschedparam(pthread_attr_t *restrict attr, const struct sched_param *restrict param);

       The  functions pthread_attr_setschedparam() and pthread_attr_getschedparam(), respectively, set and get the scheduling parameter attributes
       in the attr argument. The contents of the param structure are defined in <sched.h>. For the  SCHED_FIFO and  SCHED_RR  policies,  the  only
       required member of  param is sched_priority.

       If  successful,	the  pthread_attr_setschedparam()  and	pthread_attr_getschedparam()  functions  return   0. Otherwise, an error number is
       returned to indicate the error.

       The pthread_attr_setschedparam() function may fail if:

       EINVAL	       attr is invalid.

       The pthread_attr_getschedparam() function may fail if:

       EINVAL	       attr or	param is invalid.

USAGE

       After these attributes have been set, a thread can be created with the specified attributes using pthread_create().  Using  these  routines
       does not affect the current running thread.

       See attributes(5) for descriptions of the following attributes:

NAME

     pthread_attr_getschedparam -- get and set scheduling attributes

LIBRARY

     POSIX Threads Library (libpthread, -lpthread)

SYNOPSIS

     #include <pthread.h>

     int
     pthread_attr_getschedparam(const pthread_attr_t * restrict attr, struct sched_param * restrict param);

     int
     pthread_attr_setschedparam(pthread_attr_t *attr, const struct sched_param *param);

     int
     pthread_attr_getschedpolicy(const pthread_attr_t * restrict attr, int * restrict policy);

     int
     pthread_attr_setschedpolicy(pthread_attr_t *attr, int policy);

DESCRIPTION

     The pthread_attr_getschedparam() and pthread_attr_setschedparam() functions obtain and set the scheduling parameter attribute in the attr
     object.  The sched_param structure is defined in <sched.h>.  At minimum this structure contains only a single member, sched_priority.  Refer
     to pthread_schedparam(3) and sched(3) for additional details.

     The pthread_attr_getschedpolicy() and pthread_attr_setschedpolicy() functions get and set the scheduling policy attribute, policy, in the
     attr object.  The supported values of policy are the same ones listed in pthread_schedparam(3).

RETURN VALUES

     If successful, all described functions return 0.  Otherwise, an error number is returned to indicate the error.

ERRORS

     The pthread_attr_getschedparam() function may fail if:

     [EINVAL]		An invalid parameter was specified.

     The pthread_attr_setschedparam() function may fail if:

     [EINVAL]		An invalid parameter was specified.

     [ENOMEM]		There was insufficient memory.

     The pthread_attr_setschedpolicy() function may fail if:

     [ENOMEM]		There was insufficient memory.

     [ENOTSUP]		An unsupported policy was specified.

     No errors are defined for pthread_attr_getschedpolicy().

STANDARDS

     These functions conform to IEEE Std 1003.1-2008 (``POSIX.1'').
