                                           wsreg_set_data(3WSREG)



NAME
     wsreg_set_data, wsreg_get_data, wsreg_get_data_pairs  -  add
     or retrieve a key-value pair

SYNOPSIS
     cc [flag ...]  file ...-lwsreg [library ...]
     #include 

     int wsreg_set_data(Wsreg_component *comp, const char *key,
          const char *value);


     char *wsreg_get_data(const Wsreg_component *comp, const char *key);


     char *wsreg_get_data_pairs(const Wsreg_component *comp);


DESCRIPTION
     The wsreg_set_data() function adds the key-value pair speci-
     fied by key and value to the component specified by comp. If
     value is NULL, the key and current value is removed from the
     specified component.


     The wsreg_get_data() function retrieves the value associated
     with  the  key specified by key from the component specified
     by comp.


     The wsreg_get_data_pairs()  function  returns  the  list  of
     key-value pairs from the component specified by comp.

RETURN VALUES
     The wsreg_set_data() function returns a  non-zero  value  if
     the  specified  key-value  pair  was successfully added.  It
     returns 0 if the addition failed. If NULL is passed  as  the
     value,  the  current  key-value  pair  are  removed from the
     specified component.


     The wsreg_get_data() function returns the  value  associated
     with  the  specified  key.   It  returns NULL if there is no
     value associated with the specified key.  The  char  pointer
     that  is returned is not a clone, so it must not be freed by
     the caller.


     The  wsreg_get_data_pairs()   function   returns   a   null-
     terminated array of char pointers that represents the speci-
     fied component's list of data pairs.  The  even  indexes  of

     the  resulting  array  represent  the  key  names.   The odd
     indexes of the array represent the values. If the  specified
     component  has no data pairs, NULL is returned.  The result-
     ing array (not its contents) must be released by the caller.

USAGE
     Any string data can be associated with a component.  Because
     this  information  can  be  viewed  in  the prodreg registry
     viewer, it is a good place to store support contact informa-
     tion.


     After the data pairs are added  or  removed,  the  component
     must  be  updated  with a call to wsreg_register(3WSREG) for
     the modifications to be persistent.
