This function causes SIGSEGV when it's called with buf == NULL. Also it
returns EINVAL with mode != "a".
It appears it wasn't tested with buf == NULL at all:
/* r+/w+/a+, and no buf: file starts empty. */
c->buf = (char *) (c + 1);
*(char *) buf = '\0'; // Should be c->buf?
c->pos = c->eof = 0;
c->append = (flags & __SAPP) != 0;
This condition looks strange:
if (!size || !(buf || flags & __SAPP)) // Why?
ptr->_errno = EINVAL;
