const
Indicates that a function has no effect other than returning a value and that it uses only its arguments to generate that return value.
Syntax
Windows: __declspec(const) |
Linux: __attribute__((const)) |
Arguments
None |
Description
This keyword is equivalent to the gcc* attribute const and applies to function declarations.
