Detailed Description

Wrappers for Meschach data structures allowing use of C++ operators.

Idea:

• define for any STRUCT a class STRUCTP
• data representation of STRUCTP is compatible to STRUCT*
• overload operators as needed, esp. operator []

C synonym: typedef STRUCT* STRUCTP

Known Problem:

• Meschach prototypes have no const's –> bad const handling (VEC *v_add(VEC *a, VEC *b, VEC *out) instead of VEC *v_add(const VEC *a, const VEC *b, VEC *out)

Function Documentation

Real Mesch::sscan_real ( const char *  str )

inline
