      7 .SH SYNOPSIS
      8 .nf
      9   #include <ixp.h>
     10   
     11   uint ixp_sendmsg(int fd, IxpMsg *msg);

     16 .SH DESCRIPTION
     17 .P
     18 These functions read and write messages to and from the given
     19 file descriptors.
     20 
     21 .P
     22 ixp_sendmsg writes the data at ImsgR\->pos upto ImsgR\->end.
     23 If the call returns non\-zero, all data is assured to have
     24 been written.
     25 
     26 .P
     27 ixp_recvmsg first reads a 32 bit, little\-endian length from
     28 IfdR and then reads a message of that length (including the
     29 4 byte size specifier) into the buffer at ImsgR\->data, so
     30 long as the size is less than ImsgR\->size.
     31 
     32 .SH RETURN VALUE
     33 .P
     34 These functions return the number of bytes read or
     35 written, or 0 on error. Errors are stored in
     36 \fBixp_errbuf(3)\fR.
