SYNOPSIS

#include <graphviz/expr.h>

Expr_t* exopen(Exdisc_t*);
Excc_t* exccopen(Expr_t*, Exccdisc_t*);
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*, FILE*);
int expop(Expr_t*);
int excomp(Expr_t*, const char*, int, const char*, FILE*);
int extoken(Expr_t*);
char* extype(long int);
Extype_t exzero(long int);
