NAME
wsreg_set_unique_name, wsreg_get_unique_name - set or get the unique name of a component
SYNOPSIS
cc [flag ...] file ...-lwsreg [library ...]
#include <wsreg.h>
int wsreg_set_unique_name(Wsreg_component *comp, const char *unique_name);
char *wsreg_get_unique_name(const Wsreg_component *comp);
DESCRIPTION
The wsreg_set_unique_name() function sets the unique name specified by unique_name in the component specified by comp. Every component
must have a unique name before being registered. If a unique name has already been set in the specified component, the resources associ-
ated with the previously set unique name are released.
The wsreg_get_unique_name() function gets the unique name string from the component specified by comp. The resulting string must be
released by the caller.
RETURN VALUES
The wsreg_set_unique_name() function returns a non-zero value if the unique name was set correctly; otherwise it returns 0.
The wsreg_get_unique_name() function returns a copy of the unique name from the specified component.
