PTHREAD_CONDATTR(3)					   BSD Library Functions Manual 				       PTHREAD_CONDATTR(3)

NAME

     pthread_condattr_destroy, pthread_condattr_init -- condition attribute operations

SYNOPSIS

     #include <pthread.h>

     int
     pthread_condattr_destroy(pthread_condattr_t *attr);

     int
     pthread_condattr_init(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.

SEE ALSO

STANDARDS

     pthread_condattr_init() and pthread_condattr_destroy() conform to ISO/IEC 9945-1:1996 (``POSIX.1'')

PTHREAD_CONDATTR(3)					     Library Functions Manual					       PTHREAD_CONDATTR(3)

NAME

       pthread_condattr_init, pthread_condattr_destroy - condition creation attributes

SYNOPSIS

       #include <pthread.h>

       int pthread_condattr_init(pthread_condattr_t *attr);

       int pthread_condattr_destroy(pthread_condattr_t *attr);

DESCRIPTION

       Condition  attributes  can  be  specified  at  condition  creation  time,  by  passing  a  condition attribute object as second argument to
       pthread_cond_init(3).  Passing NULL is equivalent to passing a condition attribute object with all attributes set to their default values.

       The LinuxThreads implementation supports no attributes for conditions. The functions on condition attributes are included only for  compli-
       ance with the POSIX standard.

       pthread_condattr_init  initializes  the	condition attribute object attr and fills it with default values for the attributes.  pthread_con-
       dattr_destroy destroys a condition attribute object, which must not be reused until it is reinitialized. Both functions do nothing  in  the
       LinuxThreads implementation.

RETURN VALUE

       pthread_condattr_init and pthread_condattr_destroy always return 0.
