This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@stdlib/ndarray-base-napi-typedarray-type-to-dtype) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.
Readme
Node-API ndarray dtype
C API for returning the ndarray data type corresponding to a Node-API typed array type.
Installation
npm install @stdlib/ndarray-base-napi-typedarray-type-to-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 );
// ...
}
