EnumFontsProc

The EnumFontsProc function is an application defined callback function that processes font data from the EnumFonts function.

Parameters

lpLogFont

Points to a LOGFONT structure that contains information about the logical attributes of the font.

The LOGFONT structure has the following form:

typedef struct tagLOGFONT { /* lf */

LONG lfHeight;

LONG lfWidth;

LONG lfEscapement;

LONG lfOrientation;

LONG lfWeight;

BYTE lfItalic;

BYTE lfUnderline;

BYTE lfStrikeOut;

BYTE lfCharSet;

BYTE lfOutPrecision;

BYTE lfClipPrecision;

BYTE lfQuality;

BYTE lfPitchAndFamily;

BYTE lfFaceName[LF_FACESIZE];

} LOGFONT;

lpTextMetric

Points to a TEXTMETRIC structure that contains information about the physical attributes of the font.

The TEXTMETRIC structure has the following form:

typedef struct tagTEXTMETRIC { /* tm */

LONG tmHeight;

LONG tmAscent;

LONG tmDescent;

LONG tmInternalLeading;

LONG tmExternalLeading;

LONG tmAveCharWidth;

LONG tmMaxCharWidth;

LONG tmWeight;

LONG tmOverhang;

LONG tmDigitizedAspectX;

LONG tmDigitizedAspectY;

BYTE tmFirstChar;

BYTE tmLastChar;

BYTE tmDefaultChar;

BYTE tmBreakChar;

BYTE tmItalic;

BYTE tmUnderlined;

BYTE tmStruckOut;

BYTE tmPitchAndFamily;

BYTE tmCharSet;

} TEXTMETRIC;

nFontType

Specifies the type of the font.

lpData

Points to the application-supplied data passed by EnumFonts.

Return Value

This function must return a nonzero value to continue enumeration; to stop enumeration, it must return zero.

Comments

An application must register the EnumFontsProc function by passing its address to the EnumFonts function.

EnumFontsProc is a placeholder for the application-supplied function name. The actual name must be exported by including it in an EXPORTS statement in the application's module-definition file.
