OutputProc
The OutputProc function is an application-defined callback function that draws a string as a
result of a call to the GrayString function.
BOOL CALLBACK OutputProc(
HDC hdc,
| // handle to device context
| LPARAM lpData,
| // pointer to string to be drawn
| int cchData
| // length of string to be drawn
| );
|
|
Parameters
hdc
Identifies a device context with a bitmap of at least the width and height
specified by the nWidth and nHeight parameters passed to GrayString.
lpData
Points to the string to be drawn.
cchData
Specifies the length, in characters, of the string.
Return Values
If it succeeds, the callback function should return TRUE.
If the function fails, the return value is FALSE.
