pthread_condattr_init(3)				     Library Functions Manual					  pthread_condattr_init(3)

NAME

       pthread_condattr_init - Initializes a condition variable attributes object.

LIBRARY

       DECthreads POSIX 1003.1c Library (libpthread.so)

SYNOPSIS

       #include <pthread.h>

       int pthread_condattr_init(
			 pthread_condattr_t  *attr);

STANDARDS

       Interfaces documented on this reference page conform to industry standards as follows:

       IEEE Std 1003.1c-1995, POSIX System Application Program Interface

PARAMETERS

       Address of the condition variable attributes object to be initialized.

DESCRIPTION

       This routine initializes the condition variable attributes object specified by the (attr) argument with a set of default attribute values.

       When  an attributes object is used to create a condition variable, the values of the individual attributes determine the characteristics of
       the new condition variable.  Attributes objects act as additional arguments to condition variable creation.  Changing individual attributes
       in an attributes object does not affect any condition variables that were previously created using that attributes object.

       You  can  use  the same condition variable attributes object in successive calls to pthread_condattr_init(3), from any thread.  If multiple
       threads can change attributes in a shared attributes object, your program must use a mutex to protect  the  integrity  of  that	attributes
       object.

       Results are undefined if this routine is called and the attr argument specifies a condition variable attributes object that is already ini-
       tialized.

       The pthread_condattr_init(3) and pthread_condattr_destroy(3) routines are provided for  future  expandability  of  the  DECthreads  pthread
       interface  and  to  conform  with  the  POSIX.1c  standard.   These  routines  serve  no useful function, because there are no pthread_con-
       dattr_set*(3) type routines available at this time.

RETURN VALUES

       If an error condition occurs, this routine returns an integer value indicating the type of error.  Possible return values are  as  follows:
       Successful  completion.	 The  value  specified by attr is not a valid condition variable attributes object.  Insufficient memory exists to
       initialize the condition variable attributes object.

ERRORS

       None
