EnumFontFamiliesEx

The EnumFontFamiliesEx function enumerates all fonts in the system that match the font characteristics specified by the LOGFONT structure. EnumFontFamiliesEx enumerates fonts based on typeface name, character set, or both.

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

Handle to the device context.

lpLogfont

Pointer to a LOGFONT 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

Pointer to the application-defined callback function. For more information about the callback function, see the EnumFontFamExProc 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

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 LOGFONT 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.
