	)

Spawn new process.

Returns:

pid of new process

Forks and executes the program pointed to by program. program must be either a binary executable, or a script starting with a line of the form:

#! interpreter [optional-arg]

See execve(2) from man pages for details on the script. argv should point to the command line to pass to this program if specified. envp should point to a null-terminated array of C-strings, each of which in the form "NAME=VALUE" for the process's environment if specified.
