 * This API allows you to create a temporary object directory, advertise it to
 | 
						|
 * sub-processes via GIT_OBJECT_DIRECTORY and GIT_ALTERNATE_OBJECT_DIRECTORIES,
 | 
						|
 * and then either migrate its object into the main object directory, or remove
 | 
						|
 * it. The library handles unexpected signal/exit death by cleaning up the
 | 
						|
 * temporary directory.
 | 
						|
 *
 | 
						|
 * Example:
 | 
						|
 *
 | 
						|
 *	struct tmp_objdir *t = tmp_objdir_create();
 | 
						|
 *	if (!run_command_v_opt_cd_env(cmd, 0, NULL, tmp_objdir_env(t)) &&
 | 
						|
 *	    !tmp_objdir_migrate(t))
 | 
						|
 *		printf("success!\n");
 | 
						|
 *	else
 | 
						|
 *		die("failed...tmp_objdir will clean up for us");
