Syntax
int TransportError(HANDLE hService);
Parameters
hService
[in] Handle to a SERVICE structure.
Return Values
The sample TransportError routine returns an integer error number for the last error that occurred. If no error has occurred, TransportError must return TRANS_ERR_NONE (with associated error string “No error,” returned by TransportErrorMsg). Note that this is required for every transport service’s implementation of TransportError.
Other custom error values can be defined by the transport service. For example, the sample transport service defines the following values:
TRANS_ERR_NO_SVC_DIR
Service directory unavailable.
TRANS_ERR_HANDLE_NOT_ALLOC
Could not allocate memory for service handle.
TRANS_ERR_CANT_OPEN
Could not create message file.
TRANS_ERR_CANT_SEND
Could not open mail message.
TRANS_ERR_INV_MSG_ID
Invalid message identifier specified.
TRANS_ERR_NO_MSG_BUF
Could not allocate message buffer.
TRANS_ERR_READ
There was an error reading the message.
Remarks
The transport service provider must implement the TransportError function in a DLL registered as a mail service. The Inbox application can then load this DLL and call this function.
