| 36 This function's result is locale dependent. Unlike memcasecmp(), it works | |
| 37 correctly in multibyte locales and also handles Turkish i / dotless i. | |
| 38 Unlike ulc_casecmp(), it does not handle the German sharp s and the Greek | |
| 39 final sigma. Like memcoll() and ulc_casecoll(), it uses collation order. | |

| 41 Return a negative number if S1 < S2, a positive number if S1 > S2, 0 if | |
| 42 S1 and S2 have the same contents, or an unspecified value if there is an | |
| 43 error. | |
| 44 Set errno to an error number if there is an error, and to zero otherwise. | |
| 45 | |
| 46 Note: This function may, in multibyte locales, return 0 for strings of | |
| 47 different lengths! */ | |
