symLookup -- basic symLookup basic EMF SynopsisFinds a value from a symbol table given the lookup key.Prototype #include "uemf.h" sym_t *symLookup(sym_fd_t sd, char_t* aname); Parameters sdHandle to the table created from a previous call to symOpen. anameThe string lookup key that was set by symEnter. 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"); Stability ClassificationEvolving.See Also symClose, symDelete, symEnter, symFirst, symNext, symOpen
