Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

#define GETEXTENTTABLE 257 
short Control(lpDevice, GETEXTENTTABLE, lpInData, lpOutData)
LPPDEVICE lpDevice;
LPBYTE lpInData;
LPINT lpOutData;
 
The GETEXTENTTABLE escape returns the width (extent) of individual
characters from a group of consecutive characters in the selected font's
character set. The first and last character (from the group of consecutive
characters) are function arguments.
 
Parameter  Description
────────────────────────────────────────────────────────────────────────────
 
 
lpDevice   Points to a PDEVICE structure specifying the destination device.
 
lpInData   Points to a CHARRANGE structure containing the character codes
           for the first and last characters in the range.
 
lpOutData  Points to an array of integer values. The size of the array must
           be at least one more than the difference between the chLast and
           chFirst members of the structure pointed to by the lpInData
           parameter.
 
Return Value
 
The return value is 1 if the escape is successful. Otherwise, the return
value is 0 if it is not successful, or if the escape is not implemented.
 
Comments
 
The values returned are affected by whether relative character widths are
enabled or disabled.
