SetTextCharacterExtra function (wingdi.h)
The SetTextCharacterExtra function sets the intercharacter spacing. Intercharacter spacing is added to each character, including break characters, when the system writes a line of text.
int SetTextCharacterExtra( [in] HDC hdc, [in] int extra );
A handle to the device context.
The amount of extra space, in logical units, to be added to each character. If the current mapping mode is not MM_TEXT, the nCharExtra parameter is transformed and rounded to the nearest pixel.
If the function succeeds, the return value is the previous intercharacter spacing.
If the function fails, the return value is 0x80000000.
This function is supported mainly for compatibility with existing applications. New applications should generally avoid calling this function, because it is incompatible with complex scripts (scripts that require text shaping; Arabic script is an example of this).
