My own fuction: Access Violation error...

Hello,

I am trying to implement my own version a split function in VC6 using
a vector and strtok().

vector<char *> Split(char *input, const char *sep)
{ //implementation of VB split function using vectors
vector<char *> v;
char *token;
token = " ";
while (token != NULL)
{
token = strtok(input, sep);
v.push_back(token);
}
return v;
}

The only problem is when I trace it through the first token and I have
a space as the separator (haven't tried another separator, yet) it
crashes and burns (i.e. Access Violation) when it reaches the first
separator / space.

Am I doing something blatantly wrong?
Any suggestions to improve this function?

TIA...

.
