Access violation while pushing newnode on list

Hi all,

I have problem with pushing the node on the list.

my program is as follows

Code:

struct LinkFiles 
{
        int count;
        int index;
        wchar_t * filePath;
        wchar_t * fileName;
};

uint64_t length=0;
						struct LinkFiles newnode ;
						newnode.count = stats.f_nlink - 1;
						newnode.fileIndex=index;
						
						newnode.fileName=(vfm_char_t*)malloc(wcslen(name.c_str())+1);
						if (NULL != newnode.fileName)
						{
							wcsncpy(newnode.fileName,name.c_str(), wcslen(name.c_str())) ;
							
						}
						else 
						{
							wprintf(L"\n\n CopyIndex : newnode.fileName is null ");
							goto end ;
						}
						length = wcslen(name.c_str());
						newnode.fileName[length]=L'\0' ;
						
						newnode.filePath=(vfm_char_t*)malloc(wcslen(path.c_str())+1);
						wprintf(L"\n\n The strlen of path  is <%d> ",wcslen (path.c_str()));
						if (NULL != newnode.filePath)
						{
							wcsncpy(newnode.filePath , path.c_str(),wcslen (path.c_str()));
							
						}
						else 
						{
							wprintf(L"\n\n CopyIndex : newnode.filePath is null ");
							goto end;
						}
						length=wcslen(path.c_str());
						newnode.filePath[length]=L'\0' ;
						try 
						{
							g_linkFilesList.push_back(newnode);
						}
						catch (...)
						{
							wprintf(L"\n\n CopyIndex : Error while pushing newnode on list ");
							
						}

In this , i get an error "Access Violation : writing to location 0x00000000 "
The newnode.filePath and newnode.fileName are valid .

Please response asap.

It's really hard to say in this small snippet of code.
And since this is C++,
struct LinkFiles
can simply be written as
LinkFiles
No "struct" needed.
Moreover, don't use malloc, use new. And why are you using WIDE pointers? Use std::wstring instead.

malloc allocates bytes, wstring has 2 bytes per character. so you need to multiply your string length by sizeof( w_char)

by I do not undestand why not to use the wstring class

Thanks Vart ! It works.

Thanks Elysia ! It is my code requirement !

Thank to all for quick reply!
