- string1 IntPtr
-
The first string to compare.
- length1 Int32
-
Character length of the string indicated by string1 parameter.
If this value is '-1', the function determines the length automatically.
- string2 IntPtr
-
The second string to compare.
- length2 Int32
-
Character length of the string indicated by string2 parameter.
If this value is '-1', the function determines the length automatically.
- ignoreCase Boolean
-
True: performs a case-insensitive comparison.
False: performs a case-sensitive comparison.
Int32
Returns one of the following values if successful:
1 (CSTR_LESS_THAN):
string1 is less than
string2.
2 (CSTR_EQUAL):
string1 is equals to
string2.
3 (CSTR_GREATER_THAN):
string1 is greater than
string2.
If the function fails, the return value is zero.
