pthread_attr_set_getschedparam(3) [osx man page]

PTHREAD_ATTR(3) 					   BSD Library Functions Manual 					   PTHREAD_ATTR(3)

NAME

     pthread_attr_getschedparam, pthread_attr_setschedparam -- thread attribute operations

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 *restrict attr, const struct sched_param *restrict param);

DESCRIPTION

     Thread attributes are used to specify parameters to pthread_create().  One attribute object can be used in multiple calls to
     pthread_create(), with or without modifications between calls.

     pthread_attr_getschedparam() and pthread_attr_setschedparam() get and set the scheduling parameters within the attr argument. See
     /usr/include/sched.h
     for the definition of struct sched_param.	The sched_priority field of struct sched_param can be set to SCHED_OTHER, SCHED_FIFO and SCHED_RR.

RETURN VALUES

     If successful, these functions return 0.  Otherwise, an error number is returned to indicate the error.  pthread_attr_getschedparam(), on
     success, will copy the value of the thread's scheduling parameter attribute to the location pointed to by the second function parameter.

ERRORS

     pthread_attr_getschedparam() will fail if:

     [EINVAL]		Invalid value for attr.

     pthread_attr_setschedparam() will fail if:

     [EINVAL]		Invalid value for attr.

     [ENOTSUP]		Invalid value for param.

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);

DESCRIPTION

       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>. The only required member of param is sched_priority.

RETURN VALUES

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

ERRORS

       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.

ATTRIBUTES

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

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
