How do I trim leading/trailing whitespace in a standard way?

Question

Is there a clean, preferably standard method of trimming leading and trailing whitespace from a string in C? I\'d roll my own, but I would think this is a common problem wit

Answer 1

Another one, with one line doing the real job:

#include 

int main()
{
   const char *target = "   haha   ";
   char buf[256];
   sscanf(target, "%s", buf); // Trimming on both sides occurs here
   printf("<%s>\n", buf);
}
