TSetRslBlk

#include <PrintTraps.h>

typedef struct TSetRslBlk { Size Offset Description

short iOpCode; 2 0 4 = opcode for SetRsl

short iError ; 2 2 0=noErr; 1=noSuchRsl;

2=opNotImpl

long lReserved; 4 4 (not used )

THPrint hPrint; 4 8 Handle to a valid print record

short iXRsl; 2 12 Requested X-axis resolution

short iYRsl; 2 14 Requested Y-axis resolution

Notes: TSetRslBlk defines a subsidiary record used by the TGnlData record in

PrGeneral calls. The first 8 bytes are common for all PrGeneral calls

and, in fact, constitute the TGnlData record. HPrint is the handle to a

TPrint structure that has already been passed by PrValidate. If the call

succeeds, TPrint is updated with the resolution requested in iXRsl and

iYRsl, a 0=noErr is returned. If the request can't be satisfied, an error

code is returned (1=noSuchRsl) and the resolution fields take the values of

the printer's default resolution

(default = 0 x 0 ).

Purposely specifying an invalid resolution can be used to undo the effect of

a previous PrGeneral call since the effect will be to force the printer back

to its default.
