PfLoadFont(), PfLoadFontCx()

Preload a font within the font server

Synopsis:

#include <photon/Pf.h>
int PfLoadFont( const char *font,
                unsigned flags,
                FontName fontused );

#include <font_api.h>
int PfLoadFontCx( struct _Pf_ctrl * context,
                  const char * font,
                  unsigned flags,
                  FontName fontused );

Arguments:

context

(PfLoadFontCx() only) A pointer to the font context to use, returned by PfAttachCx() or PfAttachDllCx().

font

The name of the desired font, as created by PfGenerateFontName() or PfGenerateFontNameCx().

flags

Any combination of:

• PHFONT_LOAD_METRICS -- load the font metrics.
• PHFONT_LOAD_IMAGES -- load the font bitmaps.

If you don't specify any flags, the function checks the validity of the input font name.

fontused

NULL, or a buffer where the function can store the real name of the font, which may be different from the input if the font is unknown or is mapped as an alias to another font (via the fontmap file).
