Please be aware that csh is not well represented nor received (for good reasons) in these fora. Even I had to search this forum's man pages. Would be worthwhile reading for you as well.

pthread_condattr_init

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.
