+ * asprintf - asprintf wrapper (and if necessary, implementation).
+ *
+ * This provides a convenient wrapper for asprintf, and also implements
+ * asprintf if necessary.

+ *
+ * Example:
+ * #include <ccan/asprintf/asprintf.h>
+ * #include <unistd.h>
+ * #include <err.h>
+ *
+ * int main(int argc, char *argv[])
+ * {
+ * char *p = afmt("This program has %i arguments", argc);
+ * int ret;
+ *
+ * while ((ret = write(STDOUT_FILENO, p, strlen(p))) > 0) {
+ * p += ret;
+ * if (!*p)
+ * exit(0);
+ * }
+ * err(1, "Writing to stdout");
+ * }
