Artikel
08/24/2023

Fungsi GetIpStatistics mengambil statistik IP untuk komputer saat ini.

Sintaks

IPHLPAPI_DLL_LINKAGE ULONG GetIpStatistics(
  [out] PMIB_IPSTATS Statistics
);

Parameter

[out] Statistics

Penunjuk ke struktur MIB_IPSTATS yang menerima statistik IP untuk komputer lokal.

Menampilkan nilai

Jika fungsi berhasil, nilai yang dikembalikan NO_ERROR.

Jika fungsi gagal, nilai yang dikembalikan adalah salah satu kode kesalahan berikut.

Menampilkan kode	Deskripsi
ERROR_INVALID_PARAMETER	Parameter pStatsadalah NULL, atau GetIpStatistics tidak dapat menulis ke memori yang ditujukkan oleh parameter pStats .
Lainnya	Gunakan fungsi FormatMessage untuk mendapatkan string pesan untuk kesalahan yang dikembalikan.

Keterangan

Fungsi GetIpStatistics mengembalikan statistik untuk IPv4 pada komputer saat ini. Pada Windows XP dan yang lebih baru, GetIpStatisticsEx dapat digunakan untuk mendapatkan statistik IP untuk IPv4 atau IPv6.

Contoh

Contoh berikut mengambil statistik IPv4 untuk komputer lokal dan mencetak nilai dari data yang dikembalikan.
