Use `yrmcds_text_mode()` +to put the connection into the text protocol mode: + +```c + check_error( yrmcds_connect(&c, "localhost", 11211) ); + check_error( yrmcds_text_mode(&c) ); + + // Use the library API just in the same way as binary protocol. +``` + +Limitations: + +* Only subset of commands can be used. + + `yrmcds_get_touch`, lock related functions, `yrmcds_incr2` and + `yrmcds_decr2`, stat functions, key dump extension are not supported. + +* Quiet mutation cannot be used. + + `quiet` arguments must be 0. You need to receive a response for + every command. + +* `yrmcds_response::cas_unique` is always 0 for storage commands. + + The response for `yrmcds_set`, `yrmcds_add`, or `yrmcds_replace` + will not bring the correct CAS value.
