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

oc        Specifies the output context.

       om        Specifies the output method.

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

       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 provided.  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 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-dependent 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 argument 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 specified output context.
