Template Expansion
Once the compiler selects an expansion case, one of the following
sequences occurs:
•
If the control line contains the
error, using the first line following the
of the error message. For example, invoking the following
function as
traps(1)
asm int traps (int i)
{
% const(1) i; error;
Reached trap1
% const(2) i; error;
Reached trap2
% error;
Reached traps without 1 or 2
}
•
More than one line of template text following an
results in a compiler syntax error.
•
If the control line contains the
call to an external function using the
instruction. You can specify the name of the external function, as in
the following example:
%call my_alt_afn;
