function is an application-defined callback function that draws a string as a
result of a call to the GrayString function.
BOOL CALLBACK OutputProc(

LPARAM lpData, |
// pointer to
string to be drawn |
|
int cchData |
// length of string
to be drawn |

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

length, in characters, of the string.
Return Values

succeeds, the callback function should return TRUE.
