Application Control Flow
Application Control Flow
Figure 12-4 summarizes the control flow of the sample application:
•
The main control block establishes communication with an EMS consumer
distributor process, then calls spi_cmd_set_source().
•
The spi_cmd_set_source() function builds a SPI command that identifies the EMS
collector from which to obtain trap events and then calls send_spi_cmd() to
process the command.
•
The send_spi_cmd() function sends the SPI command to the EMS consumer
distributor and processes the response. This general-purpose function is called
from various functions whenever a SPI command is ready for processing.
•
The spi_cmd_load_filter() function builds a SPI command that identifies the filter
object file and then calls send_spi_cmd() to process the command.
