.SH NAME
pthread_condattr_init,
pthread_condattr_destroy
\-
condition creation attributes
.
.
.SH SYNOPSIS
.B #include <pthread.h>
.P
.BI "int pthread_condattr_init(pthread_condattr_t *" attr ");"
.BI "int pthread_condattr_destroy(pthread_condattr_t *" attr ");"
.
.
.SH DESCRIPTION
Condition attributes can be specified at condition creation time,
by passing a condition attribute object
as second argument to \fBpthread_cond_init\fP(3).
Passing \fBNULL\fP is equivalent to
passing a condition attribute object
with all attributes set to their default values.
.P
The LinuxThreads implementation supports no attributes for conditions.
The functions on condition attributes are
included only for compliance with the POSIX standard.
.P
\fBpthread_condattr_init\fP
initializes the condition attribute object \fIattr\fP
and fills it with default values for the attributes.
\fBpthread_condattr_destroy\fP destroys a condition attribute object,
which must not be reused until it is reinitialized.
Both functions do nothing in the LinuxThreads implementation.
.
.
.SH "RETURN VALUE"
\fBpthread_condattr_init\fP and \fBpthread_condattr_destroy\fP always return 0.
.
.
.SH "SEE ALSO"
\fBpthread_cond_init\fP(3).
