    char *gettok_prev(cli_s *cli);
    char *gettok_next(cli_s *cli);
    char *gettok_offset(cli_s *cli, int n);
    

this is a set of token-peeking utilities to access specific argv indices.

see ezcli/cli_s for what fields to fill it with.

gettok_prev()

gets the previously parsed token. if idx = 1, returns NULL.

gettok_next()

gets the next parsed token. if idx = end, returns NULL.

gettok_offset()

offsets n from the current token's position. returns NULL if the offset is too small or too large.

note: use CLI_TOK_FIRST as n for the first token in argv and CLI_TOK_LAST as n for the final token.
