What is the maximum number of commdna line arguments

[mythologyrocks]

Hi all,

Can any 1 here tell me whats the maximum # of command line arguments a C++ program can have in a multiprocessing environment, i.e. we keep creating child processes based on argc in main(int argc, char **argv)..., before v hit stack overflow error...

Thankx in advance.

It isn't dependent on the number of arguments: it is the total length of the combined arguments. On Solaris 2.6 it was around 1K.

I resorted to dumping the arguments in a file and passing that file as an argument and all the stack overflows just disappeared.
