   D_RDCURR

SUMMARY
   d_rdcurr(currbuff,cursize)
   DB_ADDR  **currbuff;
   int      *cursize;

ARGUMENTS
   currbuff  A pointer to a DB_ADDR pointer variable which will contain a
             pointer to a d_rdcurr allocated buffer which contains the
             currency table.

   currsize  A pointer to an integer variable which will contain the size of
             the buffer in bytes.

DESCRIPTION
   This function will allocate a memory buffer and copy the contents of the
   currency table (and timestamps, if used) into that buffer. A pointer to the
   copy of the currency table is returned in currbuff and the size of the
   buffer in bytes is returned in currsize. The size is provided in case the
   application needs to save the table in a file for restoration in a later
   execution of the database program.

   This functions is intended to be used whitch d_wrcurr to save and restore
   the state of a database routine before or after other routines are called
   for which it is unknown how the currency might changed.

CURRENCY CHANGES
   None.

RETURN CODES

   -904    S_NOMEMORY      Unable to allocate enough memory for currbuff


EXAMPLE

    DB_ADDR *ctab; /*save currency table*/
    int csize;     /*size of saved currency table */
    ..
    /* save currency tables */
    d_rdcurr(&ctab,&csize);
    ..     /* do some other processing */
    /* restore currency tables */
    d_wrcurr(ctab);
