EvmSrvStart(3) EvmSrvStart(3)

In each of these cases, the data is returned to the caller only if the address passed to the function as the

corresponding argument is not NULL.

The function returns a non-null value in at most one of these return arguments, and sets the others to

NULL. If the incoming message does not include data (for example, if it is a protocol message indicating

that the service is terminating) all three of the arguments are set to NULL.

The message may carry one information item, which is returned if info is not NULL. This value is used in

the service termination protocol message to indicate the exit code of the service process.

Notes

EvmSrvMessageGet

is not currently supported for general use.

RETURN VALUE

EvmERROR_NONE

If a non-null pointer was supplied as the appropriate argument, a received data

message is available in one of the three data return arguments.

EvmERROR_SERVICE_TERMINATED

The service indicated that it was terminating. If the caller passed a non-null data

argument, the service process’s exit code is returned in the info operand.

EvmERROR_EOF The service connection was closed by the service before a service termination

message was received. This value is returned if the caller continues to attempt

the call after the service has been terminated.

ERRORS

The value of errno is not set.
