/*****
 ***** Module Info

/*! \file isc/symtab.h
 * \brief Provides a simple memory-based symbol table.
 *
 * Keys are C strings, and key comparisons are case-insensitive.  A type may
 * be specified when looking up, defining, or undefining.  A type value of
 * 0 means "match any type"; any other value will only match the given
 * type.
 *
 * It's possible that a client will attempt to define a <key, type, value>
 * tuple when a tuple with the given key and type already exists in the table.
 * What to do in this case is specified by the client.  Possible policies are:
 *
 *\li	#isc_symexists_reject	Disallow the define, returning #ISC_R_EXISTS
 *\li	#isc_symexists_replace	Replace the old value with the new.  The
 *				undefine action (if provided) will be called
 *				with the old <key, type, value> tuple.
 *\li	#isc_symexists_add	Add the new tuple, leaving the old tuple in
 *				the table.  Subsequent lookups will retrieve
 *				the most-recently-defined tuple.
 *
 * A lookup of a key using type 0 will return the most-recently defined
 * symbol with that key.  An undefine of a key using type 0 will undefine the
 * most-recently defined symbol with that key.  Trying to define a key with
 * type 0 is illegal.
 *
 * The symbol table library does not make a copy the key field, so the
 * caller must ensure that any key it passes to isc_symtab_define() will not
 * change until it calls isc_symtab_undefine() or isc_symtab_destroy().
 *
 * A user-specified action will be called (if provided) when a symbol is
 * undefined.  It can be used to free memory associated with keys and/or
 * values.
 *
 * A symbol table is implemented as a hash table of lists; the size of the
 * hash table is set by the 'size' parameter to isc_symtbl_create().  When
 * the number of entries in the symbol table reaches three quarters of this
 * value, the hash table is reallocated with size doubled, in order to
 * optimize lookup performance.  This has a negative effect on insertion
 * performance, which can be mitigated by sizing the table appropriately
 * when creating it.
 *
 * \li MP:
 *	The callers of this module must ensure any required synchronization.
 *
 * \li Reliability:
 *	No anticipated impact.
 *
 * \li Resources:
 *	TBS
 *
 * \li Security:
 *	No anticipated impact.
 *
 * \li Standards:
 *	None.
