   6  * stringbuilder - join lists of strings
   7  *
   8  * This is a small set of functions for building up strings from a list.
   9  * The destination buffer is bounds-checked, the functions return failure
  10  * if the concatenated strings overflow the buffer.
  11  *
  12  * Example:
  13  *      #include <stdio.h>
  14  *      #include <string.h>
  15  *      #include <errno.h>
  16  *      #include <ccan/stringbuilder/stringbuilder.h>
  17  *
  18  *      int main(int argc, char *argv[])
  19  *      {
  20  *              char mystring[128];
  21  *              int res;
  22  *
  23  *              res = stringbuilder_array(mystring, 128, "', '",
  24  *                      argc, (const char**)argv);
  25  *              if (!res)
  26  *                      printf("My arguments: '%s'\n", mystring);
  27  *              else
  28  *                      printf("Failed to join arguments: %s\n",
  29  *                              strerror(res));
  30  *              if (!res) {
  31  *                      res = stringbuilder(mystring, 128, ", ",
  32  *                              "This", "Is", "A", "Test");
  33  *                      if (!res)
