EnumFontFamiliesEx ID_TMO

[Now Supported on Windows NT]

The EnumFontFamiliesEx function enumerates all fonts in the system that match the font characteristics specified by the LOGFONT5M4ITK structure. EnumFontFamiliesEx enumerates fonts based on typeface name, character set, or both. It is recommended that Win32-based applications use this function rather than EnumFontFamiliesZXZNX3 to enumerate fonts.

int EnumFontFamiliesEx(

HDC hdc,	// handle to device context
LPLOGFONT lpLogfont,	// pointer to logical font information
FONTENUMPROC lpEnumFontFamExProc,	// pointer to callback function
LPARAM lParam,	// application-supplied data
DWORD dwFlags	// reserved; must be zero
);

Parameters

hdc

Identifies the device context.

lpLogfont

Points to a LOGFONT5M4ITK structure that contains information about the fonts to enumerate. The function examines these members:

Member	Description
lfCharset	If set to DEFAULT_CHARSET, the function enumerates all fonts in all character sets. If set to a valid character set value, the function enumerates only fonts in the specified character set.
lfFaceName	If set to an empty string, the function enumerates one font in each available typeface name. If set to a valid typeface name, the function enumerates all fonts with the specified name.
lfPitchAndFamily	Must be set to zero for all language versions of the operating system except Hebrew and Arabic. For these languages, set IfPitchAndFamily to MONO_FONT to enumerate only fonts that provide all codepage characters within the font.

lpEnumFontFamExProc

Points to the application-defined callback function. For more information about the callback function, see the EnumFontFamExProc1B4UUSP function.

lParam

Specifies a 32-bit application-defined value. The function passes this value to the callback function along with font information.

dwFlags

Reserved; must be zero.

Return Values

If the function succeeds, the return value is the last value returned by the callback function. This value depends on which font families are available for the specified device.

Remarks

EnumFontFamiliesEx does not use tagged typeface names to identify character sets. Instead, it always passes the correct typeface name and a separate character set value to the callback function. The function enumerates fonts based on the the values of the lfCharset and lfFacename members in the LOGFONT5M4ITK structure.

If lfCharset is DEFAULT_CHARSET and lfFaceName is an empty string, the function enumerates one font in every face in every character set. If lfFaceName is not empty, the function enumerates every font in the specified typeface regardless of character set.

If lfCharset is a valid character set value and lfFaceName is an empty string, the function enumerates every font in the specified character set. If lfFaceName is not empty, the function enumerates every font having the specified typeface and character set.
