quinary

C APIs for registering a Node-API module exporting interfaces for invoking quinary numerical functions.

Usage

var headerDir = require( '@stdlib/math/base/napi/quinary' );

headerDir

Absolute file path for the directory containing header files for C APIs.

var dir = headerDir;
// returns <string>

Examples

var headerDir = require( '@stdlib/math/base/napi/quinary' );

console.log( headerDir );
// => <string>

C APIs

Usage

#include "stdlib/math/base/napi/quinary.h"

stdlib_math_base_napi_ddddd_d( env, info, fcn )

Invokes a quinary function accepting and returning double-precision floating-point numbers.

#include <node_api.h>

// ...

static double add( const double x, const double y, const double z, const double w, const double u ) {
    return x + y + z + w + u;
}

// ...

/**
* 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 ) {
    return stdlib_math_base_napi_ddddd_d( env, info, add );
}

// ...

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] double (*fcn)( double, double, double, double, double ) quinary function.
void stdlib_math_base_napi_ddddd_d( napi_env env, napi_callback_info info, double (*fcn)( double, double, double, double, double ) );

stdlib_math_base_napi_fffff_f( env, info, fcn )

Invokes a quinary function accepting and returning single-precision floating-point numbers.

#include <node_api.h>

// ...

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

// ...

/**
* 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 ) {
    return stdlib_math_base_napi_fffff_f( env, info, addf );
}

// ...

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, float, float, float ) quinary function.
void stdlib_math_base_napi_fffff_f( napi_env env, napi_callback_info info, float (*fcn)( float, float, float, float, float ) );

STDLIB_MATH_BASE_NAPI_MODULE_DDDDD_D( fcn )

Macro for registering a Node-API module exporting an interface for invoking a quinary function accepting and returning double-precision floating-point numbers.

static double add( const double x, const double y, const double z, const double w, const double u ) {
    return x + y + z + w + u;
}

// ...

// Register a Node-API module:
STDLIB_MATH_BASE_NAPI_MODULE_DDDDD_D( add );

The macro expects the following arguments:

  • fcn: double (*fcn)( double, double, double, double, double ) quinary function.

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

STDLIB_MATH_BASE_NAPI_MODULE_FFFFF_F( fcn )

Macro for registering a Node-API module exporting an interface for invoking a quinary function accepting and returning single-precision floating-point numbers.

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

// ...

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

The macro expects the following arguments:

  • fcn: float (*fcn)( float, float, float, float, float ) quinary function.

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

Notes

  • The C-API functions expect that the callback info argument provides access to the following JavaScript arguments:

    • x: input value.
    • y: input value.
    • z: input value.
    • w: input value.
    • u: input value.
