| * 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"); | |
| * | |
