CmCspGetConnectionInfo (Compact 7)
3/12/2014
This function queries a Connection Service Provider to obtain information about a connection that has an adaptor type that is managed by the Connection Service Provider.
Syntax
CM_RESULT CmCspGetConnectionInfo(
__in_bcount(CM_CONNECTION_NAME_LENGTH) WCHAR* szConnection,
__inout_bcount(*pcbInfo) CM_CSP_CONNECTION_INFO* pInfo,
__inout DWORD* pcbInfo);
Parameters
- szConnection
[in] The connection name.
- pInfo
[in, out] A pointer to a CM_CSP_CONNECTION_INFO structure that contains connection information that is available to the Connection Service Provider.
- pcbInfo
[in, out] A pointer to the number of bytes required to hold the pInfo structure, if the input parameter was not big enough.
Return Value
The following table shows the possible return values.
| Value | Description |
|---|---|
CMRE_SUCCEEDED |
The call succeeded. |
CMRE_INVALID_CONNECTION |
The connection does not exist. |
CMRE_INSUFFICIENT_BUFFER |
The structure pInfo is not large enough to contain the connection information. The required buffer size is returned in *pcbInfo. |
CMRE_UNEXPECTED |
Indicates any other failure to get connection information. |
Remarks
The structure pInfo contains information that Connection Manager has about the connection. The Connection Service Provider can update this information with more accurate values. For example, if the value of one of the characteristics is unknown (CM_UNKNOWN_CHARACTERISTIC_VALUE), the Connection Service Provider can update this value with an actual value. If the Connection Service Provider doesn't have a value for one or more of the attributes, it must leave it unchanged.
