NetBSD 6.1.5 - man page for pthread_attr_getschedparam (netbsd section 3)

PTHREAD_ATTR_GETSCHEDPARAM(3)	   BSD Library Functions Manual     PTHREAD_ATTR_GETSCHEDPARAM(3)

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().

SEE ALSO
     pthread_attr(3), pthread_schedparam(3), sched(3)

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