Hello! I'm studying the possibilities of Metamod, and I was wondering if it was possible to intercept the call of the function IBaseFileSystem::Open and call it with another parameter? I was trying to do this:

PHP Code:

SH_DECL_HOOK3(IBaseFileSystem, Open, SH_NOATTRIB, 0, FileHandle_t,  const char *, const char *, const char *); 


I announced this

PHP Code:

IBaseFileSystem *basefilesystem = NULL;
GET_V_IFACE_CURRENT(GetFileSystemFactory, basefilesystem, IBaseFileSystem, BASEFILESYSTEM_INTERFACE_VERSION); 


and add hook

PHP Code:

OpenHook = SH_ADD_VPHOOK(IBaseFileSystem, Open, basefilesystem, SH_MEMBER(this, &SamplePlugin::Hook_Open), false); 


I tried to do so

PHP Code:

FileHandle_t SamplePlugin::Hook_Open(const char *pFileName, const char *pOptions, const char *pathID) {
   if(strncmp(pFileName, "materials/headshot1.vtf", strlen("materials/headshot1.vtf")) == 0) {
         META_LOG(g_PLAPI, "yeaaa opening headshot file \"%s\",pOptions \"%s\",pathID \"%s\".", pFileName, pOptions, pathID);
          RETURN_META_VALUE_NEWPARAMS(MRES_OVERRIDE, NULL, &IBaseFileSystem::Open, ("materials/headshot2.vtf", pOptions, pathID));
   }
RETURN_META_VALUE(MRES_IGNORED, false);
} 


but not working((
If you do like this, the server is crashing

PHP Code:

FileHandle_t SamplePlugin::Hook_Open(const char *pFileName, const char *pOptions, const char *pathID) {
   if(strncmp(pFileName, "materials/headshot1.vtf", strlen("materials/headshot1.vtf")) == 0) {
    META_LOG(g_PLAPI, "yeaaa opening headshot file \"%s\",pOptions \"%s\",pathID \"%s\".", pFileName, pOptions, pathID);

    FileHandle_t myhndl = basefilesystem->Open(pFileName, pOptions, pathID);
RETURN_META_VALUE(MRES_SUPERCEDE, myhndl);
   }

RETURN_META_VALUE(MRES_IGNORED, false);

} 


What did I do wrong? I tried using MRES_OVERRIDE, but it did not help...
