Overview
The CompareStrings function compares the value of the characters between two strings and returns a result as less than, equal to, or greater than.
Syntax/Parameters
Syntax
int = CompareStrings ( string a, string b );
Parameters
a
A string to compare.
b
A string to compare.
Return Value
Returns an int value as:
| -1 | if a < b |
| 0 | if a == b |
| 1 | if a > b |
Remarks
The CompareStrings function combines the basic comparison operators (==, <, and >) to allow string comparison in a single operation. The function compares a and b on a character by character basis. If all characters matchup between the strings up to the matching terminating /0 character, the return result is 0. If any character mismatches, the comparison is stopped and -1 or 1 is returned depending on whether the character in a is less than the character at the same position in b.
Except for the terminating zero (as is the case with string types), the CompareString function essentially performs a binary, character-for-character comparison.
