Declaration¶

Source position: sysstrh.inc line 93

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 observes the locale. 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.

None.
