/**
 * stringmap - Macros for mapping strings to things
 *
 * stringmap provides a generic string map via macros.  It also supports byte
 * strings with null characters.
 *
 * Features which are sorely lacking in this version of stringmap are deletion and traversal.
 *
 * Example:
 *
 * #include <ccan/stringmap/stringmap.h>
 *
 * static const char *get_string(void) {
 *      static char buffer[4096];
 *      char *tail;
 *      if (!fgets(buffer, sizeof(buffer), stdin))
 *              return NULL;
 *      tail = strchr(buffer, 0);
 *      if (tail>buffer && tail[-1]=='\n')
 *              *--tail = 0;
 *      if (!*buffer)
 *              return NULL;
 *      return buffer;
 * }
 *
 * int main(void) {
 *      stringmap(int) map = stringmap_new(NULL);
 *      const char *string;
 *
 *      while ((string = get_string()) != NULL) {
 *              int *count = stringmap_lookup(map, string);
 *
 *              if (!count) {
 *                      printf("\"%s\" is new\n", string);
 *                      count = stringmap_enter(map, string);
 *              }
 *
 *              (*count) ++;
 *
 *              printf("\"%s\" has been entered %d times\n", string, *count);
 *      }
 *
 *      stringmap_free(map);
 *
 *    return 0;
 * }
