XCreateOC(3)			 XLIB FUNCTIONS 		    XCreateOC(3)

NAME
     XCreateOC,  XDestroyOC, XSetOCValues, XGetOCValues, XOMOfOC - create output
     contexts

SYNTAX
     XOC XCreateOC(XOM om, ...);

     void XDestroyOC(XOC oc);

     char * XSetOCValues(XOC oc, ...);

     char * XGetOCValues(XOC oc, ...);

     XOM XOMOfOC(XOC oc);

ARGUMENTS
     oc        Specifies the output context.

     om        Specifies the output method.

     ...       Specifies the variable length argument list to  set  or	get  XOC
	       values.

DESCRIPTION
     The  XCreateOC function creates an output context within the specified out-
     put method.

     The base font names argument is mandatory at creation time, and the  output
     context  will  not be created unless it is provided.  All other output con-
     text values can be set later.

     XCreateOC returns NULL if no output context could be created.  NULL can  be
     returned for any of the following reasons:

     *	  A required argument was not set.

     *	  A read-only argument was set.

     *	  An argument name is not recognized.

     *	  The  output  method encountered an output method implementation-depen-
	  dent error.

     The XDestroyOC function destroys the specified output context.

     The XSetOCValues function returns NULL if no error occurred; otherwise,  it
     returns  the name of the first argument that could not be set.  An argument
     might not be set for any of the following reasons:

     *	  The argument is read-only.

     *	  The argument name is not recognized.

     *	  An implementation-dependent error occurs.

     Each value to be set must be an appropriate datum, matching the  data  type
     imposed by the semantics of the argument.

     The  XGetOCValues function returns NULL if no error occurred; otherwise, it
     returns the name of the first argument that could not be obtained.  An  ar-
     gument might not be obtained for any of the following reasons:

     *	  The argument name is not recognized.

     *	  An implementation-dependent error occurs.

     Each  argument  value  following  a name must point to a location where the
     value is to be stored.

     The XOMOfOC function returns the output method associated with  the  speci-
     fied output context.
