name: duk_require_buffer
|
|
|
|
proto: |
|
|
void *duk_require_buffer(duk_context *ctx, duk_idx_t index, duk_size_t *out_size);
|
|
|
|
stack: |
|
|
[ ... val! ... ]
|
|
|
|
summary: |
|
|
<p>Like <code><a href="#duk_get_buffer">duk_get_buffer()</a></code>,
|
|
but throws an error if the value at <code>index</code> is not a (plain)
|
|
buffer or if the index is invalid.</p>
|
|
|
|
example: |
|
|
void *ptr;
|
|
duk_size_t sz;
|
|
|
|
ptr = duk_require_buffer(ctx, -3, &sz);
|
|
printf("buf=%p, size=%lu\n", ptr, (unsigned long) sz);
