PTHREAD_ATTR_GETSCHEDPARAM(3)                         Library Functions Manual

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'').
