General - Thread Safe
Could someone give me some pointers as to why this function is not thread safe
Code:
LPTSTR NextToken(LPTSTR p)
{
LPTSTR p1, p2;
static LPTSTR CurrTok;
if (p)
CurrTok = p;
if (CurrTok==NULL || *CurrTok==0)
return NULL;
// Run until delimeter
for (p2 = p1 = CurrTok; *p1 && *p1 != ','; p1++);
if (*p1==0)
CurrTok = NULL;
else
{
*p1 = 0;
CurrTok = p1+1;
}
return p2;
}
thanks

static LPTSTR CurrTok;
If two threads call this function they will share (and probably corrupt in some way) this variable.
