This program implements reliable transfer of data over the vfer protocol.

• 05/06/06 ivan added -vv option
• 04/30/06 ivan made to use vfer_recvfile and vfer_sendfile
• 04/12/06 ivan Added call to vfer_rcp_print_stats() at the end of each transmission and on exit
• 03/21/06 ivan Added daemonizing support and rehashed usage to include start|stop
• 02/18/06 ivan Changed name to vfer_rcpd.c. Added SIGINT handler to exit racefully, added support for daemonization via daemon() syscall - only on BSD and Linux
• 01/15/05 ivan Branched from test_sndfile.c

int parse_opts	(	int	argc,
		char **	argv,
		FILE **	testing_out
	)

Parses the command line arguments and options to main()

This function will print descriptive errors it finds to stdout

Parameters:

	argc	is the argc argument to main
	argv	is the argv argument to main
	testing_out	is a FILE** type that is either set to NULL here or to 'stdout' depending on verbosity args

Returns:

1 on success [stop service] 0 on success [start service] -1 on error -2 if help option was specified

void print_help	(	char *	prog,
		int	verbose
	)

Prints a verbose or a non-verbose usage page

Parameters:

	prog	program name to use in the help page
	verbose	controls whether the page is verbose(1) or not(0)

int rcpd_connect

(

)

This function makes preliminary api calls to vfer lib to create a listening socket

Returns:

-1 on error

0 on success

Definition at line 180 of file vfer_rcpd.c.

sig

)

This function is a catcher of SIGINT signal, installed in main()
