This function gets the first candidate connection that can be used by an application to try to connect to a destination host.

Syntax

CM_RESULT CmGetFirstCandidateConnection(
__in CM_SESSION_HANDLE hSession,
__in const WCHAR* pszHost,
__in CM_CONNECTION_SELECTION_OPTION Option,
__out CM_CONNECTION_HANDLE* phConnection
);

Parameters

  • pszHost
    [in] A pointer to a string value specifying the destination host name or IP address.

    Delimit a name with quotes. For example: "www.microsoft.com". A "*" in the leftmost label of the name will match all FQDN names in the domain. For example: "*.microsoft.com" matches "www.microsoft.com" and "msdn.microsoft.com".

    Delimit an IP address with quotes and square brackets. For example: "[207.46.19.254]". A "/" and a prefix length is used to define a CIDR block of addresses. For example: "[207.46.19.0/24]" or "[2001:0db8:1234::/48]".

  • phConnection
    [in] A pointer to a storage area to place the output.

    [out] A pointer to a CM_SESSION_HANDLE of the first candidate connection.
