Description
Defines a null-terminated string.
PChar defines a pointer to a memory location that contains WideChar values (including the #0 character).
In Delphi, one can obtain a PChar value from a string or a WideString, allowing seamless integration with C or C++ applications that expect null-terminated Unicode strings.
Note: PChar is inherently unsafe if used in combination with normal string values. PChar variables are not reference-counted and are not copy-on-written. This may result in corruption of the string values or memory leaks.
Warning: Do not cast non-character pointer types to PAnsiChar to do pointer arithmetic. Instead, use the PByte pointer type, which is declared with the {$POINTERMATH ON} compiler directive.
