From SysUtils.hpp
bool __fastcall IsPathDelimiter(System::UnicodeString S, int Index);
Unit: SysUtils
Type: function
Description
Indicates whether the byte at a specified position in a string is the path delimiter.
Call IsPathDelimiter to determine whether a position in the string S contains the path delimiter character ('/' on Linux and Macintosh, '\' on Windows). Positions are numbered from 1.
When working with a multi-byte character system (MBCS), IsPathDelimiter distinguishes between a true delimiter character, and the byte of the same value that can appear as the second byte of a double-byte character.
To test for more characters than just the delimiter, use IsDelimiter.
