with-stack-fobjects

Arguments: bind-clauses &rest body

This variant of with-stack-fobject allows multiple bindings. The bind clauses are of the form

((var1 type1 [:allocation a-val1] [:size s-val1]) 
 (var2 type2 [:allocation a-val2] [:size s-val]2) ... 
 (varn typen [:allocation a-val3] [:size s-val3]))

For each clause, allocate an object of type typeN on the stack and bind it to varN while evaluating body. The object will be of allocation type specified (default :foreign) for the purposes of accessing it with fslot-value and associated functions.

See with-stack-fobject for a detailed description of the arguments and the allocation rules.

See ftype.htm for information on foreign types in Allegro CL and foreign-functions.htm for general information on foreign functions in Allegro CL.
