how load library in windows executable

hinstance dllhandle; char str[255]; typedef int(*tfp)(char * const); dllhandle = loadlibrary("mylib.dll"); tfp fp = (tfp)getprocaddress(dllhandle, "myfunc"); fp(str); freelibrary(dllhandle); 

mydll.spec

@ stdcall myfunc(str) 

mydll.c

#include <windef.h>  int winapi myfunc(char * str) {   strcpy(str, "myfunc winelib dll");   return 0; } 

use winedebug=+module debug dll loading problems.

i don't belive wine searches native .dll.so files outside of single folder, wrong though. code in dlls/ntdll/loader.c if want check (grep load_builtin_dll).
