Description
This module implements a highly efficient generic symbol table with
update and access routines. Symbols are simple character strings and
the values they take can be flexible types as defined by value_t.
This module allows multiple symbol tables to be created.
Return Value
Returns a pointer to a sym_t structure which contains the value.
NULL if not found.
Example
sym_fd_t id;
sym_t* sp;
id = symOpen(64);
...
symEnter(id, "lookup", valueString("value"), 0);
...
sp = symLookup(id, "lookup");
