wsreg_set_data(3WSProduct Install Registry Library Functwsreg_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 <wsreg.h>
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 specified 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 specified 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 resulting
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 information.
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.
