[in] env
: The environment that the API is invoked under.[in] cbinfo
: The callback info passed into the callback function.[in-out] argc
: Specifies the length of the providedargv
array and receives the actual count of arguments.[out] argv
: Buffer to which thenapi_value
representing the arguments are copied. If there are more arguments than the provided count, only the requested number of arguments are copied. If there are fewer arguments provided than claimed, the rest ofargv
is filled withnapi_value
values that representundefined

if the API succeeded.
