__return_address
In this section:
Syntax
void * __return_address(void);
Description
Returns the address that the function will return to. For interrupt functions, the appropriate control and status register (CSR) will be read.For regular functions, the value is fetched from the link register—usually ra, but it can be a different register for static functions.
Note
To use intrinsic functions in an application, you must include the header file(s) where they are declared, see Summary of intrinsic functions.
