FILE_LICENCE

(

GPL2_OR_LATER

int execv	(	const char *	command,
		char *const	argv[]
	)

Execute command.

Parameters:

	command	Command name
	argv	Argument list

Return values:

rc

Command exit status

Execute the named command. Unlike a traditional POSIX execv(), this function returns the exit status of the command.
