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).
