proto: |
|
|
void *duk_get_buffer_data_default(duk_context *ctx, duk_idx_t idx, duk_size_t *out_size, void *def_ptr, duk_size_t def_len);

stack: |
|
|
[ ... val! ... ]
|
|
|
|
summary: |
|
|
<p>Like <code><a href="#duk_get_buffer_data">duk_get_buffer_data()</a></code>
|
|
but with an explicit default value, returned when the value is not a plain
|
|
buffer, a buffer object, or the index is invalid.</p>

<div include="default-pointer-validity.html" />

|
example: |
|
|
void *ptr;
|
|
duk_size_t sz;
|
|
char buf[256];
|
|
|
|
/* Use a buffer or buffer object given at index 2, or default to 'buf'. */
|
|
ptr = duk_get_buffer_data_default(ctx, 2, &sz, (void *) buf, sizeof(buf));
