Indeed. My understanding was that it was by analogy with assignment.
In other words, if you do this:
a = b = c;
... then 'a' gets assigned to the value that was coerced into b. In
other words, the "b = c" assignment has a value, and that value is the
same as 'b'.
The arguments in strcpy are ordered as if they're an assignment, and
they work that way:
(void) strcpy(a, strcpy(b, c));
is analogous to the assignment above.
