PTHREAD_CONDATTR(3) BSD Library Functions Manual PTHREAD_CONDATTR(3)NAME
pthread_condattr_init, pthread_condattr_destroy — condition attribute
operations
LIBRARY
POSIX Threads Library (libpthread, -lpthread)
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(). DragonFly's implementation of conditions does not
support any non-default attributes, so these functions are not very use‐
ful, though they are required 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
The pthread_condattr_init() function will fail if:
[ENOMEM] Out of memory.
The pthread_condattr_destroy() function will fail if:
[EINVAL] Invalid value for attr.

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