Detailed Description

Function Documentation

void IREC (  char *    fileName, int    mode )

Application main function. After initialization, runs forever pending on the IREC_flag semaphore. When new data is available, it is written to the IREC_out file. An incorrectly formatted frame will cause the application to halt. Parameters: fileName  The name of the output data file. mode  The ISOMAX operational mode.

void IREC_exit (  int    signal )  [static]

Cleaup application resources. This function peforms the following actions to shutdown the application: Disables the ISOMAX board. Closes the BIU_out file. Frees the output file buffer. Deletes the IREC_flag semaphore. This function is called when signal SIGTERM is sent to the application. Parameters: signal  Ignored.

int IREC_init (  char *    fileName, int    mode )  [static]

Initialize application resources. This function peforms the following actions to setup the application for operation: Opens the output file IREC_out. Allocates a buffer for the output file. Creates the IREC_flag semaphore. Configures the ISOMAX board for receiving frames. Connects IREC_intHandler() to the ISOMAX_VEC_FIFO interrupt. Attaches function IREC_exit() to the SIGTERM signal. Parameters: fileName  The name of the output data file. mode  The ISOMAX operational mode. Return values: 0  Success. -1  Failure because a resource could not be created or initialized.

void IREC_intHandler (  void    )  [static]

Frame sync interrupt handler. This function is attached to the ISOMAX frame sync board receive FIFO half-full interrupt. The newly received data is read into IREC_buf and the condition signalled through IREC_flag.
