Callback is as easy in C as in C++.
Debug iterators not needed in such simple program. At least, I don't
need them.
Here is an equivalent of your parser written in C.  It does not look 5
times longer.

Attention! That is an equivalent of Bonita's code, no more and
hopefully no less. The routine does not fulfill requirements of OP!

#include <stddef.h>

void parse(const char* src,
  void (*OnToken)(const char* beg, size_t len, void* context),
  void* context) {
  char c0 = ' ', c1 = '\t';
  const char* beg = 0;
  for (;;src++) {
    char c = *src;
    if (c == c0 || c == c1 || c == 0) {
      if (beg) {
        OnToken(beg, src-beg, context);
        c0 = ' ', c1 = '\t';
        beg = 0;
      }
      if (c == 0)
        break;
    } else if (!beg) {
      beg = src;
      if (c == '"') {
        c0 = c1 = c;
        ++beg;
      }
    }
  }
}
