The layer is now redundant, since everything left in "pkgs" is in the "racket-pkgs" category.

@title[#:tag "contmarks"]{Continuation Marks}
|
|
|
|
A mark can be attached to the current continuation frame using
|
|
@cppi{scheme_set_cont_mark}. To force the creation of a new frame
|
|
(e.g., during a nested function call within your function), use
|
|
@cppi{scheme_push_continuation_frame}, and then remove the frame with
|
|
@cppi{scheme_pop_continuation_frame}.
|
|
|
|
@function[(void scheme_set_cont_mark
|
|
[Scheme_Object* key]
|
|
[Scheme_Object* val])]{
|
|
|
|
Add/sets a continuation mark in the current continuation.}
|
|
|
|
@function[(void scheme_push_continuation_frame
|
|
[Scheme_Cont_Frame_Data* data])]{
|
|
|
|
Creates a new continuation frame. The @var{data} record need not be
|
|
initialized, and it can be allocated on the C stack. Supply @var{data} to
|
|
@cpp{scheme_pop_continuation_frame} to remove the continuation frame.}
|
|
|
|
@function[(void scheme_pop_continuation_frame
|
|
[Scheme_Cont_Frame_Data* data])]{
|
|
|
|
Removes a continuation frame created by @cpp{scheme_push_continuation_frame}.}
