NAME

       ixp_srv_readbuf, ixp_srv_writebuf

SYNOPSIS

       #include <ixp_srvutil.h>

       void ixp_srv_readbuf(Ixp9Req *req, char *buf, uint len);

       void ixp_srv_writebuf(Ixp9Req *req, char **buf, uint *len, uint max);

DESCRIPTION

       Utility  functions  for  handling  TRead and TWrite requests for files backed by in-memory
       buffers. For both functions, buf points to a buffer and len specifies the  length  of  the
       buffer.  In the case of ixp_srv_writebuf, these values add a level of pointer indirection,
       and updates the values if they change.

       If max has a value other than 0, ixp_srv_writebuf will truncate any writes to  that  point
       in the buffer. Otherwise, *buf is assumed to be malloc(3) allocated, and is reallocated to
       fit the new data as necessary. The buffer is is always left nul-terminated.

BUGS

       ixp_srv_writebuf always truncates its buffer to the end of the most recent write.
