proto: |
|
|
void *duk_opt_pointer(duk_context *ctx, duk_idx_t idx, void *def_value);
|
|
|
|
stack: |
|
|
[ ... val! ... ]
|
|
|
|
summary: |
|
|
<p>Get the pointer value at <code>idx</code> as <code>void *</code> without
|
|
modifying or coercing the value. If the value is <code>undefined</code> or
|
|
the index is invalid, <code>def_value</code> default value is returned.
|
|
In other cases (<code>null</code> or non-matching type) throws an error.</p>

example: |
|
|
void *ptr;
|
|
|
|
ptr = duk_opt_pointer(ctx, -3, (void *) 0x12345678);

printf("my pointer is: %p\n", ptr);
