		FILE **	out
	)

FIXME Fast process invocation.

FIXME mention there is no pipe close, we rely on SIGPIPE to kill the child fast_popen opens a process for execution, providing its output on a stream, just like the standard popen. However, fast_popen does not invoke the shell the interpret the command, which can be very time consuming. Thus, the command must be given as a full path, and may not include quotes, variables, or other features of the shell.

Parameters:

command

The command string to execute.

Returns:

A pointer to a file stream which must be closed with fast_pclose.
