A Gateway token represents a single connection to a specific Gateway daemon.
When a connection to a Gateway daemon is made, all subsequent API calls that retrieve statistical data must include the Gateway token as a parameter.
The statistics API handler in a Gateway daemon is restricted to five connection threads. This means that a single Gateway daemon can only deal with five connected statistics API programs, or threads, at the same time.
A statistical API program should avoid holding more than one connection to the same Gateway daemon at the same time.
A statistical API program can hold multiple Gateway tokens,
but can only use them on the thread that called the openGatewayConnection or openRemoteGatewayConnection in order to retrieve the token.
A Gateway token type (CTG_GatewayToken_t) is defined in the C-language header files.
