A caller can give a buf that is NUL terminated but specify that the only early part of the buffer to be used by giving you a shorter size, no? In such a case, strstr() is safe in the sense that it is guaranteed not to go on forever, but you need to verify the location of the string it found is within the bounds. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
