49 | ** The parameter must have a value of "unsigned char" or EOF. |
50 | ** So on platforms where a char is signed, this may give problems or at |
51 | ** least warnings. The wrapper functions below will have an "char" parameter |
52 | ** but handle it correctly. They will NOT work for EOF, but this is not a |
53 | ** problem, since EOF is always handled separately. |
