| int8_t rdline_char_in | ( | struct rdline * | rdl, | |
| char | c | |||
| ) |
append a char to the readline buffer. Return 1 when the line has been validated. Return 2 when the user asked to complete the buffer. Return -1 if it is not running. Return -2 if EOF (ctrl-d on an empty line). Else return 0. XXX error case when the buffer is full ?
| rdl | A pointer to a struct rdline | |
| c | The character to append |
