PTHREAD_CONDATTR(3)     NetBSD 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().  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_init() shall fail if:

     [ENOMEM]           Insufficient memory exists to initialize the condition
                        attribute object.

     pthread_condattr_destroy() may fail if:

     [EINVAL]           The value specified by attr is invalid.
