GetCharWidth32 info Overview Group

The GetCharWidth32 function retrieves the widths, in logical coordinates, of consecutive characters in a specified range from the current font.

BOOL GetCharWidth32(

HDC hdc,

// handle of device context

UINT iFirstChar,

// first character in range to query

UINT iLastChar,

// last character in range to query

LPINT lpBuffer

// address of buffer for widths

);

Parameters

hdc: Identifies the device context.
iFirstChar: Specifies the first character in the group of consecutive characters.
iLastChar: Specifies the last character in the group of consecutive characters, which must not precede the specified first character.
lpBuffer: Points to a buffer to receive the widths.

If the function succeeds, the return value is nonzero.

If the function fails, the return value is zero. To get extended error information, call GetLastError.

The range is inclusive; that is, the returned widths include the widths of the characters specified by the iFirstChar and iLastChar parameters.

If a character does not exist in the current font, it is assigned the width of the default character.
