Descriptionmemio are a set of routines that allow you to handle misaligned
data. A arbitrarely sized buffer, pointed to by buf, in memory is used.
From this location seqeantial access using the memXread() routines can
be done, although the usual kind of memseek() operations (see also fseek(3)
or seek(2)) allow flexible (re)location within this buffer. memclose()
free’s up the memory allocated by memopen().
BugsSome forms of out-of-memory
are not detected. Others cause error(3NEMO) to be called, that generally
abort the program. LimitationsThe buffer buf that was opened by memopen
should not be free’d or modified, otherwise unpredictable things may happen.
