NAME
       expr(1,3,n) - c-like expression library

SYNOPSIS
              #include <graphviz/expr.h>

              Expr_t*          exopen(Exdisc_t*);
              Excc_t*          exccopen(Expr_t*, Exccdisc_t*);
              int              excc(Excc_t*, const char*, Exid_t*, int);
              int              exccclose(Excc_t*);
              void             exclose(Expr_t*, int);
              char*            excontext(Expr_t*, char*, int);
              void             exerror(const char*, ...);
              Extype_t         exeval(Expr_t*, Exnode_t*, void*);
              Exnode_t*        exexpr(Expr_t*, const char*, Exid_t*, int);

              Exnode_t*        excast(Expr_t*, Exnode_t*, int, Exnode_t*, int);
              Exnode_t*        exnewnode(Expr_t*, int, int, int, Exnode_t*, Exnode_t*);
              void             exfreenode(Expr_t*, Exnode_t*);
              int              expush(Expr_t*, const char*, int, const char*, Sfio_t*);
              int              expop(Expr_t*);
              int              excomp(Expr_t*, const char*, int, const char*, Sfio_t*);
              int              exrewind(Expr_t*);
              void             exstatement(Expr_t*);
              int              extoken(Expr_t*);
              char*            extype(int);
              Extype_t         exzero(int);



DESCRIPTION
       exopen()  is the first function called.  exclose() is the last function
       called.  exccopen() is the called if(3,n)  code  generation  will  be  used.
       exccclose()  releases  the  state  information allocated in(1,8) exccopen().
       exstatement() saves statement start information.   exrewind()  restores
       statement start information saved by exstatement().
