|
.Sh DESCRIPTION
|
|
Condition attribute objects are used to specify parameters to
|
|
.Fn pthread_cond_init .
|
|
FreeBSD's implementation of conditions does not support any non-default
|
|
attributes, so these functions are not very useful, though they are required to
|
|
to be present by
|
|
.Tn POSIX .
|
|
.Pp
|
|
The
|
|
.Fn pthread_condattr_init
|
|
function initializes a condition attribute object with the default attributes.
|
|
.Pp
|
|
The
|
|
.Fn pthread_condattr_destroy
|
|
function destroys a condition attribute object.
|
|
.Sh RETURN VALUES
|
|
If successful, these functions return 0.
|
|
Otherwise, an error number is returned to indicate the error.
|
|
.Sh ERRORS
|
|
.Fn pthread_condattr_init
|
|
will fail if:
|
|
.Bl -tag -width Er
|
|
