My function will be called thousands of times. If i want to make it faster, will changing the local function variables to static be of any use? My logic behind this is that, because static variables are persistent between function calls, they are allocated only the first time, and thus, ...

1. static variables The type specifier static variable is static. Static variables, of course, belong to static storage, but the amount of static storage is not always static. For example, although external variables are static storage, they are not necessarily static variables. They must be ...

Static global variables are not visible outside of the C file they are defined in. Static functions are not visible outside of the C file they are defined in. QUESTION - static variables are local in scope to the block or file in which they are defined, but their lifespan is throughout...
and scope of a variable is defined by its storage class. The following are four types of storage class available in C language. auto register extern static In this article, we will discuss the ‘static’ storage class and explain how to use static variables and static functions in C [......
In general, work vectors are recommended over static or global variables if your S-function needs persistent memory storage. For more information on this, see the "Writing S-Functions" manual. However, if you need to use such variables, you should be...
functions and variables instead of static function and variables inside classes. However, by doing that one would forsake all member access control features of C++. And these features are really worth having. C language has no access control features, meaning that in C one loses [almost] ...
