GLYPH_GetClass()¶

GLYPH_GetClass -- Gets the pointer to the glyph class.

Synopsis

glyph_class = GLYPH_GetClass();
D0

Class * GLYPH_GetClass(VOID);

Function

    Obtains the pointer to the glyph image class for use with
    NewObject().  This function always returns a valid pointer so
    you do not need to check it.  The reason is that if the library
    opens fine, then the pointer returned is already setup.  (Of course
    this implies that if opening the library fails, you shouldn't be
    calling this.)

    Note that this function does not create the class, that is done
    when the class library is opened.

Inputs

    Nothing.

RESULT
    glyph_class - Pointer to the glyph image class.
