105 What we have is an internal buffer, which is 8 characters
106 longer than the actually used buffer. E.g. say BUFSIZ is
107 512 bytes, then we actually allocate 520 bytes. The first
108 2 characters will be junk, the next 2 characters set to NUL,
109 for protection against some backward-compares. The fourth-last
110 character is set to '\n', to protect against overscan. The
111 last 3 characters will be junk, to protect against memory
112 violation. intBuffer is the internal buffer, but everyone refers
113 to fbuf, which is actually set to the &intBuffer[4]. Also,
114 szfbuf is the size of the "visible" buffer, not the internal
115 buffer. The reason for the 2 junk characters at the beginning
116 is to align the buffer on a 4-byte boundary.
