AnsiCompareStr

Compare 2 ansistrings, case sensitive, ignoring accents characters.

Declaration

Source position: sysstrh.inc line 92

function AnsiCompareStr(

const S1: string;

const S2: string

):Integer;

Description

AnsiCompareStr compares two strings and returns the following result:

< 0: if S1<S2.
0: if S1=S2.
> 0: if S1>S2.

The comparison takes into account Ansi characters, i.e. it takes care of strange accented characters. Contrary to AnsiCompareText, the comparison is case sensitive.

Remark:

A widestring manager must be installed in order for this function to work correctly with various character sets.

Errors

None.
