- * tal - compact tree allocator routines (inspired by talloc)
- *
- * Tal is a hierarchical allocator; any pointer allocated by tal can
- * become the parent of another allocation.  When you free that parent,
- * the children (and grandchildren, etc) are automatically freed.
- *
- * This allows you to build complex objects based on their lifetimes, eg:
- *
- *  struct foo *X = tal(NULL, struct foo);
- *  X->val = tal(X, int);
- *
- * and the pointer X->val would be a "child" of the tal context "X";
- * tal_free(X->val) would free X->val as expected, by tal_free(X) would
- * free X and X->val.
- *
- * With an overhead of approximately 4 pointers per object
- * (vs. talloc's 12 pointers), it uses dynamic allocation for
- * destructors and child lists, so those operations can fail.  It does
- * not support talloc's references or failing destructors.
- *
- * See Also:
- *	ccan/tal/str (useful string helpers)
- *
- * Example:
- *	#include <stdio.h>
- *	#include <err.h>
- *	#include <ccan/tal/tal.h>
- *
- *	// A structure containing a popened command.
- *	struct command {
- *		FILE *f;
- *		char *command;
- *	};
- *
- *	// When struct command is freed, we also want to pclose pipe.
- *	static void close_cmd(struct command *cmd)
- *	{
- *		pclose(cmd->f);
- *	}
- *
- *	// This function opens a writable pipe to the given command.
- *	static struct command *open_output_cmd(const tal_t *ctx,
- *					       const char *a0, const char *a1)
- *	{
- *		struct command *cmd = tal(ctx, struct command);
- *
- *		if (!cmd)
- *			return NULL;
- *
- *		// Note that tal/str has helpers to make this much easier!
- *		cmd->command = tal_arrz(cmd, char, strlen(a0) + strlen(a1) + 2);
- *		if (!cmd->command) {
- *			tal_free(cmd);
- *			return NULL;
- *		}
- *		strcat(cmd->command, a0);
- *		strcat(cmd->command, " ");
- *		strcat(cmd->command, a1);
- *
- *		cmd->f = popen(cmd->command, "w");
- *		if (!cmd->f) {
- *			tal_free(cmd);
- *			return NULL;
- *		}
- *		tal_add_destructor(cmd, close_cmd);
- *		return cmd;
- *	}
- *
- *	int main(int argc, char *argv[])
- *	{
- *		struct command *cmd;
- *
- *		if (argc != 2)
- *			errx(1, "Usage: %s <command>\n", argv[0]);
- *
- *		cmd = open_output_cmd(NULL, argv[1], "hello");
- *		if (!cmd)
- *			err(1, "Running '%s hello'", argv[1]);
- *		fprintf(cmd->f, "This is a test\n");
- *		tal_free(cmd);
- *		return 0;
