#### STDLIB_ASSERT_NAPI_STATUS_OK_RET_VOID( env, call, message )

Macro for asserting that a Node-API API call returns an "ok" status.

`c
#include

static void foo( const napi_env env, const napi_value value, double *out ) {
// ...

STDLIB_ASSERT_NAPI_STATUS_OK_RET_VOID( env, napi_get_value_double( env, value, out ), "" )

// ...

return;
}
`

The macro expects the following arguments:

- env: environment under which the function is invoked.
- call: expression which returns a Node-API status.
- message: error message.

If a status is not "ok", an exception is raised and void returned.

#### STDLIB_ASSERT_NAPI_STATUS_OK_RET_NULL( env, call, message )

Macro for asserting that a Node-API API call returns an "ok" status.

`c
#include

static napi_value foo( const napi_env env, const napi_value value, double *out ) {
// ...

STDLIB_ASSERT_NAPI_STATUS_OK_RET_NULL( env, napi_get_value_double( env, value, out ), "" )

// ...

return NULL;
}
`

The macro expects the following arguments:

- env: environment under which the function is invoked.
- call: expression which returns a Node-API status.
- message: error message.

If a status is not "ok", an exception is raised and NULL returned.

#### STDLIB_ASSERT_NAPI_STATUS_OK_RET_VALUE( env, call, message, value )

Macro for asserting that a Node-API API call returns an "ok" status.

`c
#include

static double foo( const napi_env env, const napi_value value ) {
// ...

double *out;
STDLIB_ASSERT_NAPI_STATUS_OK_RET_VALUE( env, napi_get_value_double( env, value, out ), "", 0.0/0.0 )

// ...

return *out;
}
`

The macro expects the following arguments:

- env: environment under which the function is invoked.
- call: expression which returns a Node-API status.
- message: error message.
- value: return value.

If a status is not "ok", an exception is raised and the value specified by value returned.
