NAME
pthread_condattr_init,
pthread_condattr_destroy, —
condition attribute
operations
SYNOPSIS
#include
<pthread.h>
int
pthread_condattr_init(pthread_condattr_t
*attr);
int
pthread_condattr_destroy(pthread_condattr_t
*attr);
DESCRIPTION
Condition attribute objects are used to specify parameters to
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 POSIX.
The
pthread_condattr_init()
function initializes a condition attribute object with the default
attributes.
The
pthread_condattr_destroy()
function destroys a condition attribute object.
RETURN VALUES
If successful, these functions return 0. Otherwise, an error number is returned to indicate the error.
ERRORS
pthread_condattr_destroy() will fail
if:
- [
EINVAL] - Invalid value for attr.
pthread_condattr_init() will fail if:
- [
ENOMEM] - Out of memory.

STANDARDS
The pthread_condattr_init() and
pthread_condattr_destroy() functions conform to
ISO/IEC 9945-1:1996 (“POSIX.1”)
