kandi X-RAY | FreeFem-sources Summary

FreeFem-sources is a C++ library typically used in Simulation applications. FreeFem-sources has no bugs, it has no vulnerabilities and it has low support. However FreeFem-sources has a Non-SPDX License. You can download it from GitHub.

FreeFEM is a partial differential equation solver for non-linear multi-physics systems in 2D and 3D using the finite element method. Problems involving partial differential equations from several branches of physics such as fluid-structure interactions require interpolations of data on several meshes and their manipulation within one program. FreeFEM includes a fast interpolation algorithm and a language for the manipulation of data on multiple meshes. It is written in C++ and the FreeFEM language is a C++ idiom.

What's the difference between var and &(*var)

QUESTION

What's the difference between var and &(*var)

Asked 2018-May-19 at 14:23

Some source code use the notation &(*var) where var is already a pointer, like int *var = ....

Is there a difference between this two notations ?

Is var != &(*var) ?

Example: https://github.com/FreeFem/FreeFem-sources/blob/develop/src/medit/inout_popenbinaire.c#L40

&(*var) might have had undefined behavior when var (a pointer variable) does not contain a valid address for old versions of C. Be scared in that case. But C11 standard §6.5.3.2 states that the compiler has to handle it as equivalent in all cases (including when var is NULL)

So var == &(*var) is true when var contains a valid address. When it contains something else (e.g. NULL), it might crash (segmentation fault) if you use a non-C11 conforming non-optimizing compiler (but most compilers, even old ones, won't generate some crashing code in that case)

But the compiler (even an old C99 one) is allowed (under as-if rule) to optimize &(*var) into var
