- * noerr - routines for cleaning up without blatting errno
- *
- * It is a good idea to follow the standard C convention of setting errno in
- * your own helper functions. Unfortunately, care must be taken in the error
- * paths as most standard functions can (and do) overwrite errno, even if they
- * succeed.
- *
- * Example:
- * #include <sys/types.h>
- * #include <sys/stat.h>
- * #include <fcntl.h>
- * #include <stdbool.h>
- * #include <string.h>
- * #include <errno.h>
- * #include <ccan/noerr/noerr.h>
- *
- * bool write_string_to_file(const char *file, const char *string)
- * {
- * int ret, fd = open(file, O_WRONLY|O_CREAT|O_EXCL, 0600);
- * if (fd < 0)
- * return false;
- * ret = write(fd, string, strlen(string));
- * if (ret < 0) {
- * // Preserve errno from write above.
- * close_noerr(fd);
- * unlink_noerr(file);
- * return false;
- * }
- * if (close(fd) != 0) {
- * // Again, preserve errno.
- * unlink_noerr(file);
- * return false;
- * }
- * // A short write means out of space.
- * if (ret < strlen(string)) {
- * unlink(file);
- * errno = ENOSPC;
- * return false;
- * }
- * return true;
- * }
