6  * stringmap - Macros for mapping strings to things
7  *
8  * stringmap provides a generic string map via macros.  It also supports byte
9  * strings with null characters.
10  *
11  * Features which are sorely lacking in this version of stringmap are deletion and traversal.
12  *
13  * Example:
14  *
15  * #include <ccan/stringmap/stringmap.h>

17  * static const char *get_string(void) {                                                                                                                                        
18  *      static char buffer[4096];                                                                                                                                               
19  *      char *tail;                                                                                                                                                             
20  *      if (!fgets(buffer, sizeof(buffer), stdin))
