oracular (3) assign.3.gz

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.
