Typedefs
typedef double(*	GiNaC::FUNCP_1P) (double)
	Function pointer with one function parameter.
typedef double(*	GiNaC::FUNCP_2P) (double, double)
	Function pointer with two function parameters.
typedef void(*	GiNaC::FUNCP_CUBA) (const int *, const double[], const int *, double[])
	Function pointer for use with the CUBA library (http://www.feynarts.de/cuba).

Functions
void	GiNaC::compile_ex (const ex &expr, const symbol &sym, FUNCP_1P &fp, const std::string filename="")
	Takes an expression and produces a function pointer to the compiled and linked C code equivalent in double precision.
void	GiNaC::compile_ex (const ex &expr, const symbol &sym1, const symbol &sym2, FUNCP_2P &fp, const std::string filename="")
	Takes an expression and produces a function pointer to the compiled and linked C code equivalent in double precision.
void	GiNaC::compile_ex (const lst &exprs, const lst &syms, FUNCP_CUBA &fp, const std::string filename="")
	Takes an expression and produces a function pointer to the compiled and linked C code equivalent in double precision.
void	GiNaC::link_ex (const std::string filename, FUNCP_1P &fp)
	Opens an existing so-file and returns a function pointer of type FUNCP_1P to the contained function.
void	GiNaC::link_ex (const std::string filename, FUNCP_2P &fp)
	Opens an existing so-file and returns a function pointer of type FUNCP_2P to the contained function.
void	GiNaC::link_ex (const std::string filename, FUNCP_CUBA &fp)
	Opens an existing so-file and returns a function pointer of type FUNCP_CUBA to the contained function.
void	GiNaC::unlink_ex (const std::string filename)
	Closes all linked .so files that have the supplied filename.
