PTHREAD_ATTR_GETINHERITEDSCHED(3)			   BSD Library Functions Manual 			 PTHREAD_ATTR_GETINHERITEDSCHED(3)

NAME
     pthread_attr_getinheritedsched -- get and set ``inheritsched'' attribute

LIBRARY
     POSIX Threads Library (libpthread, -lpthread)

SYNOPSIS
     #include <pthread.h>

     int
     pthread_attr_getinheritsched(const pthread_attr_t * restrict attr, int * restrict inheritsched);

     int
     pthread_attr_setinheritsched(pthread_attr_t *attr, int inheritsched);

DESCRIPTION
     The pthread_attr_getinheritsched() and pthread_attr_setinheritsched() functions get and set, respectively, the inherit scheduler attribute,
     inheritsched, in the attr object.	The inheritsched parameter specifies whether a tread created by using attr will obtain its scheduling
     attributes directly from attr or whether it will inherit these from the calling thread.

     Two values are possible for inheritsched:

	   PTHREAD_INHERIT_SCHED   The thread scheduling attributes will be inherited from the creating thread and the ones in attr are ignored.

	   PTHREAD_EXPLICIT_SCHED  The thread scheduling attributes will be set to the corresponding values in attr.

     The following thread scheduling attributes are affected by inheritsched:

	   o   Scheduling policy; see pthread_attr_setschedpolicy(3).

	   o   Scheduling parameter; see pthread_attr_getschedparam(3).

	   o   Scheduling contention scope; see pthread_attr_getscope(3).

RETURN VALUES
     If successful, both functions return 0.  Otherwise, an error number is returned to indicate the error.

COMPATIBILITY
     The standard leaves it unspecified which (if any) is the default inherit scheduler attribute in a newly initialized attribute object.

ERRORS
     No errors are defined for pthread_attr_getinheritsched().

     The pthread_attr_setinheritsched() function may fail if:

     [EINVAL]		The value specified by inheritsched is invalid.

SEE ALSO
     pthread_attr(3)

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