However,\nthe problem is that \"bytes_left\" is type ssize_t while sizeof() is type\nsize_t.  That means that because of type promotion, the comparison is\ndone as an unsigned and if we have negative bytes left the loop\ncontinues instead of ending."

Sin embargo, el problema es que \"bytes_left\" es del tipo ssize_t mientras que sizeof() es del tipo size_t.
