Standard C Library Functions     pthread_attr_getinheritsched(3C)



NAME
     pthread_attr_getinheritsched, pthread_attr_setinheritsched -
     get or set inheritsched attribute

SYNOPSIS
     cc -mt [ flag... ] file... -lpthread [ library... ]
     #include 

     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     functions     pthread_attr_setinheritsched()     and
     pthread_attr_getinheritsched(),  respectively,  set  and get
     the inheritsched attribute in the attr argument.


     When the attribute objects are used by pthread_create(), the
     inheritsched  attribute  determines how the other scheduling
     attributes of the created thread are to be set:

     PTHREAD_INHERIT_SCHED      Specifies  that  the   scheduling
                                policy  and associated attributes
                                are  to  be  inherited  from  the
                                creating thread, and the schedul-
                                ing attributes in this attr argu-
                                ment are to be ignored.


     PTHREAD_EXPLICIT_SCHED     Specifies  that  the   scheduling
                                policy  and associated attributes
                                are to be set to the  correspond-
                                ing  values  from  this attribute
                                object.



     The        symbols         PTHREAD_INHERIT_SCHED         and
     PTHREAD_EXPLICIT_SCHED    are    defined   in   the   header
     .

RETURN VALUES
     If  successful,   the   pthread_attr_setinheritsched()   and
     pthread_attr_getinheritsched()  functions  return  0. Other-
     wise, an error number is returned to indicate the error.

Standard C Library Functions     pthread_attr_getinheritsched(3C)



     The            pthread_attr_setinheritsched()             or
     pthread_attr_getinheritsched() functions may fail if:

     EINVAL    attr or inheritsched 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.
