name: duk_require_stack
|
|
|
|
proto: |
|
|
void duk_require_stack(duk_context *ctx, duk_idx_t extra);
|
|
|
|
summary: |
|
|
<p>Like <code><a href="#duk_check_stack">duk_check_stack()</a></code> but an
|
|
error is thrown if the value stack needs to be reallocated and that
|
|
reallocation fails.</p>
|
|
|
|
<p>As a general rule, callers should use this function to reserve more
|
|
stack space. If value stack cannot be extended, there is almost never a
|
|
useful recovery strategy except to throw an error and unwind.</p>
|
|
|
|
example: |
|
|
duk_idx_t nargs;
|
|
|
|
nargs = duk_get_top(ctx); /* number or arguments */
|
|
|
|
/* reserve space for one temporary for each input argument */
|
|
duk_require_stack(ctx, nargs * 2);
