Replaces the currently running program with the program, specified in path. It gives the program the options in argvp. This is a pointer to an array of pointers to null-terminated strings. The last pointer in this array should be nil. The current environment is passed to the program. On success, execv does not return.
On error, -1 is returned. Extended error information can be retrieved with fpGetErrNo
