NAME 
-------------------------------------------------------------------------------------------- 
 
rmr_str2meid 
 
SYNOPSIS 
-------------------------------------------------------------------------------------------- 
 
 
:: 
  
 #include <rmr/rmr.h>
 int rmr_str2meid( rmr_mbuf_t* mbuf, unsigned char* src, int len )
 
 
 
DESCRIPTION 
-------------------------------------------------------------------------------------------- 
 
The rmr_str2meid function will copy the string pointed to by 
src to the managed entity ID (meid) field in the given 
message. The field is a fixed length, gated by the constant 
RMR_MAX_MEID and if string length is larger than this value, 
then **nothing** will be copied. (Note, this differs slightly 
from the behaviour of the lrmr_bytes2meid() function.) 
 
RETURN VALUE 
-------------------------------------------------------------------------------------------- 
 
On success, the value RMR_OK is returned. If the string 
cannot be copied to the message, the return value will be one 
of the errors listed below. 
 
ERRORS 
-------------------------------------------------------------------------------------------- 
 
If the return value is not RMR_OK, then it will be set to one 
of the values below. 
 
 
 
RMR_ERR_BADARG 
   
  The message, or an internal portion of the message, was 
  corrupted or the pointer was invalid. 
   
 
RMR_ERR_OVERFLOW 
   
  The length passed in was larger than the maximum length of 
  the field; only a portion of the source bytes were copied.
