Here is a piece of program which was well compiled with THINK C 3.0 :
---
Boolean condition;
pascal TPPrDlg MyJobDlgInit(hPrint)
THPrint hPrint;
{
...
}
Boolean My_PrJobDialog()
{
Boolean value;
if (condition)
value = PrDlgMain(print_record_hdle, &MyJobDlgInit);
else
value = PrDlgMain(print_record_hdle, &PrJobInit);
return value;
}
---
I have added an #include <PrintTraps.h> to compile with THINK C 4.0
and the compiler refuse "&PrJobInit" (illegal "adress of" operator).
N.B. PrJobInit is a function in the toolbox.
There is a simple way to fix the problem in this particular case : replace
the second call of PrDlgMain by "PrJobDialog(print_record_hdle);" which do the
same thing (references :Printing Manager and Macintosh Technical Note #95).
Nevertheless the problem seems to be an anomaly in the compiler.

PrJobInit is a function in the toolbox. I suspect (but haven't checked) that PrJobInit is a "Toolbox glue" routine that is defined as an in-line function (i.e., a piece of assembler that is inserted in your program) rather than as a normal addressable routine. I believe that this capability was added to Think C 4.0. You can check by looking at the source of <PrintTraps.h>. >There is a simple way to fix the problem in this particular case : replace >the second call of PrDlgMain by "PrJobDialog(print_record_hdle);" which do the >same thing (references :Printing Manager and Macintosh Technical Note #95). >Nevertheless the problem seems to be an anomaly in the compiler. More likely, it's something missing or unclear in the documentation. Martin Minow minow@bolt.enet.dec.com
