Node-API ndarray dtype

Usage

#include "stdlib/ndarray/base/napi/typedarray_type_to_dtype.h"

stdlib_ndarray_napi_typedarray_type_to_dtype( napi_typedarray_type vtype )

Returns the ndarray data type corresponding to a Node-API typed array type.

#include "stdlib/ndarray/base/napi/typedarray_type_to_dtype.h"
#include "stdlib/ndarray/dtypes.h"
#include <node_api.h>
#include <assert.h>

// Add-on function export...
napi_value addon( napi_env env, napi_callback_info info ) {

    // ...

    // Get function arguments...
    size_t argc = 1;
    napi_value argv[ 1 ];
    napi_status status = napi_get_cb_info( env, info, &argc, argv, NULL, NULL );
    assert( status == napi_ok );

    // ...

    // Get a typed array argument...
    napi_typedarray_type vtype;
    size_t xlen;
    void *X;
    status = napi_get_typedarray_info( env, argv[ 0 ], &vtype, &xlen, &X, NULL, NULL );
    assert( status == napi_ok );

    // ...

    // Return the corresponding ndarray data type for the input typed array:
    enum STDLIB_NDARRAY_DTYPE dtype = stdlib_ndarray_napi_typedarray_type_to_dtype( vtype );
