  NAME

      pthread_condattr_create - Creates a condition variable attributes
                                object

  SYNOPSIS

      #include <pthread.h>

      int pthread_condattr_create(pthread_condattr_t *attr);

  PARAMETERS

      attr                Condition variable attributes object that is
                          created.

  DESCRIPTION

  The pthread_condattr_create() routine creates a condition variable
  attributes object that is used to specify the attributes of condition
  variables when they are created. The condition variable attributes
  object is initialized with the default value for all of the attributes
  defined by a given implementation.

  When a condition variable attributes object is used to create a condi-
  tion variable, the values of the individual attributes determine the
  characteristics of the new object. Attributes objects act like addi-
  tional parameters to object creation. Changing individual attributes
  does not affect objects that were previously created using the attri-
  butes object.

  RETURN VALUES

  The created condition variable attributes object is returned to the attr
  parameter.

  If the function fails, errno may be set to one of the following values:

    Return   Error      Description
    ___________________________________________________________
    0                   Successful completion.

    -1     [EINVAL]     The value specified by attr is invalid.

    -1     [ENOMEM]     Insufficient memory exists to create
                        the condition variable attributes object.
