28 \fBint\fR \fBpthread_attr_setscope\fR(\fBpthread_attr_t *\fR\fIattr\fR, \fBint\fR \fIcontentionscope\fR);
34 The \fBpthread_attr_setscope()\fR and \fBpthread_attr_getscope()\fR functions
35 are used to set and get the \fIcontentionscope\fR attribute in the \fIattr\fR
39 The \fIcontentionscope\fR attribute can have the value
40 \fBPTHREAD_SCOPE_SYSTEM\fR, signifying system scheduling contention scope, or
41 \fBPTHREAD_SCOPE_PROCESS\fR, signifying process scheduling contention scope.
44 The symbols \fBPTHREAD_SCOPE_SYSTEM\fR and \fBPTHREAD_SCOPE_PROCESS\fR are
45 defined by the header <\fBpthread.h\fR>.
49 If successful, the \fBpthread_attr_setscope()\fR and
50 \fBpthread_attr_getscope()\fR functions return \fB0\fR. Otherwise, an error
51 number is returned to indicate the error.
55 The \fBpthread_attr_setscope()\fR, or \fBpthread_attr_getscope()\fR, function
63 \fIattr\fR or \fIcontentionscope\fR is invalid.
69 After these attributes have been set, a thread can be created with the
70 specified attributes using \fBpthread_create()\fR. Using these routines does
71 not affect the current running thread.
