Lexicographically compares two strings of Unicode code points.
| pszStr1 | A zero-terminated string that is the first (left) comparand. |
| pszStr2 | A zero-terminated string that is the second (right) comparand. |
pszStr1 is lexicographically less than pszStr2, 0, if the strings are equal, and a positive value, if pszStr1 is lexicographically greater than pszStr2.
