AnsiStrUpper

Convert a null-terminated string to all-uppercase characters.

Declaration

Source position: sysstrh.inc line 101

function AnsiStrUpper(

  Str: PChar

):PChar;

Description

AnsiStrUpper converts the PCharStr to uppercase characters and returns the resulting string. Note that Str itself is modified, not a copy, as in the case of AnsiUpperCase. It takes into account the operating system language settings when doing this, so special characters are converted correctly as well.

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

Errors

None.
