Node-API ndarray dtype

C API for returning the ndarray data type corresponding to a data type string.

Installation

npm install @stdlib/ndarray-base-napi-dtype-string-to-dtype

Usage

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

stdlib_ndarray_napi_dtype_string_to_dtype( const char *str )

Returns the ndarray data type corresponding to a data type string.

#include "stdlib/ndarray/base/napi/dtype_string_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, nullptr, nullptr );
    assert( status == napi_ok );

    // ...

    // Get a string argument...
    char str[ 1024 ];
    size_t len;
    status = napi_get_value_string_utf8( env, argv[ 0 ], (char *)str, 1024, &len );
    assert( status == napi_ok );

    // ...

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

    // ...

}
