BOOL IcmpCloseHandle( HANDLE IcmpHandle );
If the handle is closed successfully the return value is TRUE, otherwise FALSE. Call the GetLastError function for extended error information.
The IcmpCloseHandle function is exported from the Icmp.dll on Windows 2000. The IcmpCloseHandle function is exported from the Iphlpapi.dll on Windows XP and later. Windows version checking is not recommended to use this function. Applications requiring portability with this function across Windows 2000, Windows XP, Windows Server 2003 and later Windows versions should not statically link to either the Icmp.lib or the Iphlpapi.lib file. Instead, the application should check for the presence of IcmpCloseHandle in the Iphlpapi.dll with calls to LoadLibrary and GetProcAddress. Failing that, the application should check for the presence of IcmpCloseHandle in the Icmp.dll with calls to LoadLibrary and GetProcAddress.
Note that the include directive for Iphlpapi.h header file must be placed before the Icmpapi.h header file.
The following example opens and closes a handle on which ICMP echo requests can be issued.
#include <windows.h> #include <iphlpapi.h> #include <icmpapi.h> #include <stdio.h>
