Try something like this (untested):
char [][] argv = {
"ls", NULL
};
vte_terminal_fork_command(VTE_TERMINAL(vte), "ls", argv, NULL, ".", FALSE,
FALSE, FALSE);
If I recall well the first "ls" is actually the name you want the users to
see when they run ps while argv[0] has the name of the program to execute.

If that's true than one can bypass malloc. I think that you can request memory through mmap by using MAP_ANONYMOUS.
