Re: [fpc-pascal] Pointer to a const char

[Antonio Fortuny]

Le 04/11/2013 14:18, Alexander a écrit : How can I describe a "pointer to a constant char" in FreePascal? For example this C function: int some_func(const char *arg, ...); ... coulb be translated to some_proc(const arg: PChar, ...); where the argument cannot be changed in any way (the compiler complains) but the data to which the argument points can be freely changed, thus: (arg + offset)^ := #0; works I don't know a way to make the data pointed to, as being constant. Have a look at http://www.freepascal.org/docs-html/ref/refsu61.html#x160-17000014.4.4 Antonio. My guess in FreePascal is this(with ctypes unit): function some_func(const arg: pcchar): cint; cdecl; external; A constant argument to a function. I'm not sure, is it a "constant pointer to a char", or a "pointer to a constant char". The first one applies. -- Alex _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal -- Antonio Fortuny Senior Software engineer 220, avenue de la Liberté L-4602 Niederkorn Tel.: +352 58 00 93 - 93 www.sitasoftware.lu
