Function Documentation

main()

int main	(	const int	argc,
		char *	argv[]
	)

Reads a NOAAPORT data stream, creates LDM data-products from the stream, and inserts the data-products into an LDM product-queue.

The NOAAPORT data stream can take the form of multicast UDP packets from (for example) a Novra S300 DVB-S2 receiver or the standard input stream.

Usage: noaaportIngester [-l log] [-n|-v|-x] [-q queue] [-u n] [-m mcastAddr] [-I ip_addr] [-b npages]
Where:

-b npages

Allocate npages pages of memory for the internal buffer.

-I ip_addr

Listen for multicast packets on interface ip_addr. Default is the system's default multicast interface.

-l log

Log to file log. The default is to use the system logging daemon if the current process is a daemon; otherwise, the standard error stream is used.

-m mcastAddr

Use the multicast address mcastAddr. The default is to read from the standard input stream.

-n

Log messages of level NOTE and higher priority. Each data-product will generate a log message.

-q queue

Use queue as the pathname of the LDM product-queue. The default is to use the default LDM pathname of the product-queue.

-R bufSize

Set the receive buffer size for the NOAAPort UDP packets to bufSize bytes. The default is system dependent.

-u n

If logging is to the system logging daemon, then use facility localn. The default is to use the LDM facility.

-v

Log messages of level INFO and higher priority.

-x

Log messages of level DEBUG and higher priority.

If neither -n, -v, nor -x is specified, then logging will be restricted to levels ERROR and WARN only.

Return values

0	if successful.
1	if an error occurred. At least one error-message will be logged.

Parameters
