assign(3)

NAME
assign - assign an integer value, check for truncation

SYNTAX
#include <libowfat/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.
