Error: unknown type name ‘caddr_t’

This error occurs when the compiler encounters the use of an undeclared type name ‘caddr_t’. It means that the compiler doesn’t recognize the ‘caddr_t’ as a valid type.

To fix this error, you need to include the appropriate header file that defines the ‘caddr_t’ type.

Example:
    
#include <sys/types.h>

int main() {
    caddr_t address = NULL;
    // rest of the code
    return 0;
}

In this example, the ‘sys/types.h’ header file is included to define the ‘caddr_t’ type. Without including this header file, the compiler wouldn’t recognize ‘caddr_t’, resulting in the mentioned error.
