CreateProcess question

[jdoe]

Hi,

Somebody can confirm me this about the lpCommandLine parameter of CreateProcess Win32 API.

The maximum length of this string is 32K characters.

            Windows 2000:  The maximum length of this string is MAX_PATH characters.

Why the length fall this low on Windows 2000 ? It must be an error, no ?

:snooty:

p.s. Sorry, I can't have a hand on a Windows 2000 box, so I can't verify by myself.

Testing under Windows 2000 SP4, passing a 32767-byte command line, the called app received 32764 bytes.

I beleive it only affects calling a program that would open using NTVDM, because it's DOS restriction.

I'm working on something that need to be compatible from 2000 and higher and I was not sure that my call to CreateProcess would fails because the command line I'm passing is higher then MAX_PATH.


Thanks Michael for taking the time to test it. It's appreciated.
