BOOL GetCharWidth( UINT nFirstChar, UINT nLastChar, LPINT lpBuffer ) const;
nFirstChar
Specifies the first character in a consecutive group of characters in the current font.
nLastChar
Specifies the last character in a consecutive group of characters in the current font.
lpBuffer
Points to a buffer that will receive the width values for a consecutive group of characters in the current font.
Retrieves the widths of individual characters in a consecutive group of characters from the current font. For example, if nFirstChar identifies the letter 'a' and nLastChar identifies the letter 'z', the function retrieves the widths of all lowercase characters.
The function stores the values in the buffer pointed to by lpBuffer. This buffer must be large enough to hold all of the widths. For example, there must be at least 26 entries in the example given in the previous paragraph.
If a character in the consecutive group of characters does not exist in a particular font, it will be assigned the width value of the default character.
TRUE if the function is successful; otherwise FALSE.
