#### stdlib_napi_create_int32( env, value, \*out )

Converts a signed 32-bit integer to a Node-API value.

`c
#include "stdlib/napi/create_int32.h"
#include

static napi_value addon( napi_env env, napi_callback_info info ) {

// ...

napi_value value;
napi_status status = stdlib_napi_create_int32( env, 1, &value );
assert( status == napi_ok );
if ( err != NULL ) {
assert( napi_throw( env, err ) == napi_ok );
return NULL;
}

// ...
}
`

The function accepts the following arguments:

- env: [in] napi_env environment under which the function is invoked.
- value: [in] int32_t signed 32-bit integer.
- out: [out] napi_value* destination for storing output value.

`c
napi_status stdlib_napi_create_int32( const napi_env env, const int32_t value, napi_value *out );
`

The function returns a napi_status status code indicating success or failure (returns napi_ok if success).

#### STDLIB_NAPI_CREATE_INT32( env, expression, name )

Macro for converting a signed 32-bit integer to a Node-API value.

`c
#include "stdlib/napi/create_int32.h"
#include "stdlib/napi/argv_int32.h"
#include "stdlib/napi/argv.h"
#include
#include

static int32_t fcn( const int32_t v ) {
return v;
}

// ...

static napi_value addon( napi_env env, napi_callback_info info ) {
// Retrieve add-on callback arguments:
STDLIB_NAPI_ARGV( env, info, argv, argc, 1 );

// Convert the first argument to a C type:
STDLIB_NAPI_ARGV_INT32( env, value, argv, 0 );

// ...

// Convert a value having a C type to a Node-API value:
STDLIB_NAPI_CREATE_INT32( env, fcn( value ), out );

return out;
}
`

The macro expects the following arguments:

- env: environment under which the callback is invoked.
- expression: expression returning a signed 32-bit integer.
- name: output variable name.
