That is a Windows 95 function. The results of both what you report and what
I tried imply that XP does not support it.
I tried both the assembly code you posted and the following C code in large
model using TC 2 under XP Pro.
----------------------
#include <stdio.h>
#include <dos.h>
char app_title[2048];
int main()
{
int result;
_ES = FP_SEG(app_title);
_DI = FP_OFF(app_title);
_CX = sizeof(app_title);
_DX = 2;
_AX = 0x168E;
geninterrupt(0x2F);
result = _AX;
printf("%X\n\"%s\"\n", result, app_title);
return 0;
}
----------------------
If it succeeds, AX should return with the value 1or 0 for
success or failure.
When the above code is run it shows this:
""
168E
This implies that the interrupt was not executed - that the DOS
virtual machine only did a return.
