* .../c-lib/inc/min-buf.h - trivial buffer routines.
* only use these for
* encoding - if you know you 'buffer' is big enough
* to hold the encoded value
*
* decoding - if you know that the encoding is error
* free.
*
*
* The minimal buffer is simply a block of mem referenced
* by a char **(ie BUF_TYPE char**). These are very efficient
* but should only be used when it is safe (see above) or you're
* willing to risk reading past the end of the buffer or writing
* 'past' the beginning (segmentation faults/bus errors etc).
*
* No checks for reading or writing past the buffer are done.
* every operation is assumed to succeed.
