23 \fBint *restrict\fR \fIinheritsched\fR);
28 \fBint\fR \fBpthread_attr_setinheritsched\fR(\fBpthread_attr_t *\fR\fIattr\fR, \fBint\fR \fIinheritsched\fR);
34 The functions \fBpthread_attr_setinheritsched()\fR and
35 \fBpthread_attr_getinheritsched()\fR, respectively, set and get the
36 \fIinheritsched\fR attribute in the \fIattr\fR argument.
39 When the attribute objects are used by \fBpthread_create()\fR, the
40 \fIinheritsched\fR attribute determines how the other scheduling attributes of
41 the created thread are to be set:
45 \fB\fBPTHREAD_INHERIT_SCHED\fR \fR
48 Specifies that the scheduling policy and associated attributes are to be
49 inherited from the creating thread, and the scheduling attributes in this
50 \fIattr\fR argument are to be ignored.
56 \fB\fBPTHREAD_EXPLICIT_SCHED\fR \fR
59 Specifies that the scheduling policy and associated attributes are to be set to
60 the corresponding values from this attribute object.
65 The symbols \fBPTHREAD_INHERIT_SCHED\fR and \fBPTHREAD_EXPLICIT_SCHED\fR are
66 defined in the header \fB<pthread.h>\fR\&.
70 If successful, the \fBpthread_attr_setinheritsched()\fR and
71 \fBpthread_attr_getinheritsched()\fR functions return \fB0\fR. Otherwise, an
72 error number is returned to indicate the error.
76 The \fBpthread_attr_setinheritsched()\fR or
77 \fBpthread_attr_getinheritsched()\fR functions may fail if:
84 \fIattr\fR or \fIinheritsched\fR is invalid.
90 After these attributes have been set, a thread can be created with the
91 specified attributes using \fBpthread_create()\fR. Using these routines does
92 not affect the current running thread.
