int GetTextCharacterExtra(

HDC hdc |

); |

If the function fails, the return value is 0x8000000. To get extended error information, call GetLastError.
The intercharacter spacing defines the extra space, in logical units along the base line, that the TextOut or ExtTextOut functions add to each character as a line is written. The spacing is used to expand lines of text.
