NAME

       ixp_sendmsg, ixp_recvmsg

SYNOPSIS

       #include <ixp.h>

       uint ixp_sendmsg(int fd, IxpMsg *msg);

       uint ixp_recvmsg(int fd, IxpMsg *msg);

DESCRIPTION

       These functions read and write messages to and from the given file descriptors.

       ixp_sendmsg writes the data at msg->pos upto msg->end.  If the call returns non-zero, all data is assured
       to have been written.

       ixp_recvmsg  first  reads  a 32 bit, little-endian length from fd and then reads a message of that length
       (including the 4 byte size specifier) into the buffer at msg->data, so long as  the  size  is  less  than
       msg->size.

RETURN VALUE

       These  functions  return  the  number  of  bytes  read  or  written,  or 0 on error. Errors are stored in
       ixp_errbuf(3).
