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

SYNTAX
     cc [ flag... ] file... -lX11 [ library... ]

     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 output method.

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

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

     +o    A required argument was not set.

     +o    A read-only argument was set.

     +o    An argument name is not recognized.

     +o    The output method encountered an output method
          implementation-dependent error.

     The XDestroyOC function destroys the specified output con-
     text.

     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:

     +o    The argument is read-only.

     +o    The argument name is not recognized.

     +o    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 argument might not be obtained
     for any of the following reasons:

     +o    The argument name is not recognized.

     +o    An implementation-dependent error occurs.

     Each argument value following a name must point to a loca-
     tion where the value is to be stored.

     The XOMOfOC function returns the output method associated
     with the specified output context.
