57 \fBint\fR \fBpthread_attr_getinheritsched\fR(\fBconst pthread_attr_t *restrict\fR \fIattr\fR,
58 \fBint *restrict\fR \fIinheritsched\fR);
63 \fBint\fR \fBpthread_attr_setinheritsched\fR(\fBpthread_attr_t *\fR\fIattr\fR, \fBint\fR \fIinheritsched\fR);
69 The functions \fBpthread_attr_setinheritsched()\fR and
70 \fBpthread_attr_getinheritsched()\fR, respectively, set and get the
71 \fIinheritsched\fR attribute in the \fIattr\fR argument.
74 When the attribute objects are used by \fBpthread_create()\fR, the
75 \fIinheritsched\fR attribute determines how the other scheduling attributes of
76 the created thread are to be set:
80 \fB\fBPTHREAD_INHERIT_SCHED\fR \fR
83 Specifies that the scheduling policy and associated attributes are to be
84 inherited from the creating thread, and the scheduling attributes in this
85 \fIattr\fR argument are to be ignored.
91 \fB\fBPTHREAD_EXPLICIT_SCHED\fR \fR
94 Specifies that the scheduling policy and associated attributes are to be set to
95 the corresponding values from this attribute object.
100 The symbols \fBPTHREAD_INHERIT_SCHED\fR and \fBPTHREAD_EXPLICIT_SCHED\fR are
101 defined in the header \fB<pthread.h>\fR\&.
105 If successful, the \fBpthread_attr_setinheritsched()\fR and
106 \fBpthread_attr_getinheritsched()\fR functions return \fB0\fR. Otherwise, an
107 error number is returned to indicate the error.
111 The \fBpthread_attr_setinheritsched()\fR or
112 \fBpthread_attr_getinheritsched()\fR functions may fail if:
119 \fIattr\fR or \fIinheritsched\fR is invalid.
125 After these attributes have been set, a thread can be created with the
126 specified attributes using \fBpthread_create()\fR. Using these routines does
127 not affect the current running thread.
