assign.3

NAME

assign - assign an integer value, check for truncation

SYNTAX

#include <rangecheck.h>

int assign(dest,a);

DESCRIPTION

If a and dest have the same type, or the value of a is representable in the type of dest, do dest=a and return 0.

Otherwise, return 1.

Note: This is a macro, so dest does not have to be a pointer.

BUGS

In the multiplication functions, a return value of 1 signals success and 0 failure. In add_of, sub_of and assign it's the other way around.
