Re: LoadLibrary("cygx11-6.dll") results in STATUS_ACCESS_VIOLATION
here's my piece of code:
int main(int argc,char **argv)
{
HINSTANCE hInst = LoadLibrary("cygwin1.dll");
void *(*pfdlOpen)(char *,int) = (void *(*)(char
*,int))GetProcAddress(hInst,"dlopen");
int (*pfdlClose)(void *) =
(int(*)(void*))GetProcAddress(hInst,"dlclose");
void *(*pfdlSym)(void *,const char *) = (void *(*)(void *,const char
*))GetProcAddress(hInst,"dlsym");
void * hXInst = pfdlOpen("cygwin1.dll",RTLD_LAZY);
if (hInst)
{
Display *(*pfXOpenDisplay)(char *) = NULL;
pfXOpenDisplay = (Display *(*)(char *))pfdlSym(hXInst,"XOpenDisplay");
if(pfXOpenDisplay)
{
Display *pxDisplay = NULL;
pxDisplay = pfXOpenDisplay("127.0.0.1:0.0");
if(pxDisplay)
{
}
else
{
printf("Could not connect to X Server");
}
}
pfdlClose(hXInst);
}
}
note that I am using MSVC 6

Thank you for your replies.
I tried the dlopen and it gets into an inifinite loop. Any idea why?
