Title: VirtualAllocEx
Post by: MuteClown on February 17, 2011, 04:00:22 pm

I am unable to use VirtualAllocEx, i am using the Windows and SysUtils units.

Error: Identifier not found "VirtualAllocEx

Is what i am getting, i know its a kernel32 function, am i not using the right units or is it located some where else? Or maybe not implemented any where?

You mean:

Code: [Select]

uses
  ctypes;

{ links to somecfunc defined in a library someclib (libsomeclib.so on
  Linux, someclib.dll on Windows, someclib.dylib on Mac, or
  libsomeclib.a if static) }
function somecfunc(c: cint): cint; cdecl; external 'someclib';
{ links to myfunc defined in a library alib with, but you access it
  with localfunc symbol (useful when function name conflicts with
  Pascal keywords) }
procedure localfunc; stdcall; external 'alib' name 'myfunc';

Thanks!

I just moved from VB.NET to Pascal and many of my programs had a heavy use of API calls.

added virtualallocex in trunk.

Consider adding bugreports for missing calls, specially if they are relatively common used.
