Value | Meaning | |
ok | completed the conversion | |
partial | not all source characters converted | |
error | encountered a character in [from, from_end)
that cannot be converted | |
noconv | internT and externT are the same type, and input
sequence is identical to converted sequence |
result do_unshift(stateT& state, externT* to, externT* to_end, externT*& to_next) const;
Value | Meaning | |
ok | completed the sequence | |
partial | space for more than to_end - to destination elements was needed
to terminate a sequence given the value of state | |
error | an unspecified error has occurred | |
noconv | no termination is needed for this state_type |
