Hello,

Is this something known about, or: What am I missing?

TIA,
rip

PROBLEM:

man strstr says: returns char *
test code throws warning on line 7:
test.c:7: warning: assignment makes pointer from integer \
       without a cast


TEST CODE
int main (int argc, void ** argv)
{
   char *pBlah = 0x0;
   char rudolph[64] = "Rudolph the Red Nosed Reindeer";
   char red[4] = "Red";

   pBlah = strstr(rudolph, red);

   printf("1: %s\n", rudolph);
   printf("2: %s\n", red);
   printf("3: %s\n", pBlah);
}
