smap2

Usage

#include "stdlib/strided/napi/smap2.h"

stdlib_strided_napi_smap2( env, info, fcn )

Invokes a strided array interface which applies a binary callback to single-precision floating-point strided input arrays and assigns results to a single-precision floating-point strided output array.

#include <node_api.h>

// ...

static float addf( const float x, const float y ) {
    return x + y;
}

// ...

/**
* Receives JavaScript callback invocation data.
*
* @param env    environment under which the function is invoked
* @param info   callback data
* @return       Node-API value
*/
napi_value addon( napi_env env, napi_callback_info info ) {
    stdlib_strided_napi_smap2( env, info, addf );
    return NULL;
}

// ...

The function accepts the following arguments:

• env: [in] napi_env environment under which the function is invoked.
• info: [in] napi_callback_info callback data.
• fcn: [in] float (*fcn)( float, float ) binary callback.

void stdlib_strided_napi_smap2( napi_env env, napi_callback_info info, float (*fcn)( float, float ) );

STDLIB_STRIDED_NAPI_MODULE_SMAP2( clbk )

Macro for registering a Node-API module exporting a strided array interface for applying a binary callback to single-precision floating-point strided input arrays and assigning results to a single-precision floating-point strided output array.

static float addf( const float x, const float y ) {
    return x + y;
}

// ...

// Register a Node-API module:
STDLIB_STRIDED_NAPI_MODULE_SMAP2( addf );

The macro expects the following arguments:

• clbk: float (*fcn)( float, float ) binary callback.

When used, this macro should be used instead of NAPI_MODULE. The macro includes NAPI_MODULE, thus ensuring Node-API module registration.
