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.
