The GetCharWidthFloat function retrieves the fractional widths of consecutive characters in a specified range from the current font.
BOOL GetCharWidthFloat(
HDC hdc, // handle to device context
UINT iFirstChar, // first-character code point
UINT iLastChar, // last-character code point
PFLOAT pxBuffer // pointer to buffer that receives width-values
);
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero.
Windows NT: To get extended error information, call GetLastError.
The returned widths are in the 32-bit IEEE floating-point format. (The widths are measured along the base line of the characters.)
If the iFirstChar parameter identifies the letter a and the iLastChar parameter identifies the letter z, GetCharWidthFloat retrieves the widths of all lowercase characters.
If a character does not exist in the current font, it is assigned the width of the default character.
