int rmr_bytes2meid( rmr_mbuf_t* mbuf, unsigned char* src, int len )

&h2(DESCRIPTION)
The &cw(rmr_bytes2meid) function will copy up to &ital(len) bytes from &ital(src) to the
managed entity ID (meid) field in the message.
The field is a fixed length, gated by the constant &cw(RMR_MAX_MEID) and if len is larger
than this value, only RMR_MAX_MEID bytes will actually be copied.


&h2(RETURN VALUE)
On success, the actual number of bytes copied is returned, or -1 to indicate a hard error.
If the length is less than 0, or not the same as length passed in, &cw(errno) is set
to one of the errors described in the &ital(Errors) section.

&h2(ERRORS)
If the returned length does not match the length passed in, &cw(errno) will be set to one
of the following constants with the meaning listed below.

&beg_dlist(.75i : ^&bold_font )
&half_space
&di(EINVAL) The message, or an internal portion of the message, was corrupted or the pointer was invalid.

&half_space
&di(EOVERFLOW) The length passed in was larger than the maximum length of the field; only a portion of
    the source bytes were copied.
