FetchMessage Method
Fetches a single message over the specified receiver link.
Syntax
void __fastcall FetchMessage(String LinkName);
Remarks
When FetchMessage is called, the component will supply the sender with a single credit and then block until a message is received (if the FetchTimeout property is set to zero).
If FetchTimeout is non-zero, the component will only block for the specified number of seconds; once that time expires, it will instruct the sender to consume the credit. If the sender chooses to consume the credit by incrementing the value of the LinkDeliveryCount property rather than by sending a message, then the component will throw an error indicating a timeout.
LinkName specifies the receiver link which should fetch a message; if there is no such link, if the specified link is not a receiver link, or if the specified receiver link is not operating in rmSyncGet (1) mode, an error is thrown.
Refer to ReceiveMode and FetchTimeout for more information.
