47 .TH PTHREAD_SETCANCELTYPE 3C "Mar 23, 2005"
49 pthread_setcanceltype \- set cancellation type of a thread
53 cc -mt [ \fIflag\fR... ] \fIfile\fR... -lpthread [ \fIlibrary\fR... ]
56 \fBint\fR \fBpthread_setcanceltype\fR(\fBint\fR \fItype\fR, \fBint *\fR\fIoldtype\fR);
62 The \fBpthread_setcanceltype()\fR function atomically sets the calling thread's
63 cancellation type to the specified \fBtype\fR and, if \fIoldtype\fR is not
64 \fINULL,\fR stores the previous cancellation \fBtype\fR in \fIoldtype\fR. The
65 \fBtype\fR can be either of the following:
69 \fB\fBPTHREAD_CANCEL_DEFERRED\fR \fR
73 This is the default. When cancellation is enabled (enabled cancellation is also
74 the default), cancellation occurs when the target thread reaches a cancellation
75 point and a cancel is pending. When cancellation is disabled, all cancellation
76 requests to the target thread are held pending.
82 \fB\fBPTHREAD_CANCEL_ASYNCHRONOUS\fR \fR
86 When cancellation is enabled, receipt of a \fBpthread_cancel\fR(3C) call
87 causes immediate cancellation. When cancellation is disabled, all cancellation
88 requests to the target thread are held pending; as soon as cancellation is
89 re-enabled, pending cancellations are executed immediately.
94 See \fBcancellation\fR(5) for the definition of a cancellation point and a
95 discussion of cancellation concepts. See \fBpthread_setcancelstate\fR(3C) for
96 explanations of enabling and disabling cancellation.
99 The \fBpthread_setcanceltype()\fR function is a cancellation point if
100 \fBtype\fR is called with \fBPTHREAD_CANCEL_ASYNCHRONOUS\fR and the
101 cancellation state is \fBPTHREAD_CANCEL_ENABLE.\fR
105 Upon successful completion, the \fBpthread_setcanceltype()\fR function returns
106 \fB0\fR. Otherwise, an error number is returned to indicate the error.
110 The \fBpthread_setcanceltype()\fR function will fail if:
117 The specified \fBtype\fR is not \fBPTHREAD_CANCEL_DEFERRED\fR or
118 \fBPTHREAD_CANCEL_ASYNCHRONOUS.\fR
