tt_feature_enabled(library call)										  tt_feature_enabled(library call)

NAME

       tt_feature_enabled -- determine if a particular feature has been enabled in this process

SYNOPSIS

       #include <Tt/tt_c.h>
       Tt_status tt_feature_enabled(
       Tt_feature feature);

DESCRIPTION

       The  tt_feature_enabled	function  queries the ToolTalk service to see if the specified feature has previously been enabled.  This allows a
       library that "wraps around" ToolTalk for sending and receiving messages to determine if multithreaded execution has  been  enabled  by  the
       main program, and to modify its behavior accordingly.

ARGUMENTS

       feature	 Specifies the feature whose enabled status is to be checked.

RETURN VALUE

       Upon completion, the tt_feature_enabled function returns the status of the operation as one of the following Tt_status values:

       TT_OK	 The feature has been enabled previously.

       TT_WRN_NOT_ENABLED
		 The feature has not yet been enabled

       TT_ERR_UNIMP
		 The version of the ToolTalk library linked with the calling code does not support the indicated feature.

APPLICATION USAGE

       A  library using ToolTalk could check to see if the calling application had previously turned on ToolTalk's multithreading feature with the
       following code:

       Tt_status ttstat;
       ttstat = tt_feature_enabled(TT_FEATURE_MULTITHREADED);
       if (ttstat != TT_OK) {
	 ttstat = tt_feature_required(TT_FEATURE_MULTITHREADING);
       }
