The EngComputeGlyphSet function computes the glyph set supported on a device.

Syntax

ENGAPI FD_GLYPHSET * EngComputeGlyphSet(
  [in] INT nCodePage,
  [in] INT nFirstChar,
  [in] INT cChars
);

Parameters

[in] nCodePage

Specifies the code page supported.

[in] nFirstChar

Specifies the character code of the first supported ANSI character.

[in] cChars

Specifies the number of ANSI characters supported.

Return value

If the glyph set is computed successfully, the function returns a pointer to an FD_GLYPHSET structure. If an error occurs, the function returns NULL.

Remarks

A driver can use EngComputeGlyphSet to compute the glyph set for a font that contains only glyphs in the code page described by nCodePage.

The driver must call EngFreeMem to free memory when it is done using the FD_GLYPHSET structure returned by EngComputeGlyphSet.
