app_main_common.h File Reference

Process-wide runtime setup shared by every one of this example's binaries (main.c for A/B, main_c.c for C) - OSAdapter registration, checksum/watchdog/log init, signal handlers, and the REBOOT safe-state handler. Split out so this ~70-line sequence is written once instead of duplicated across both main() entry points now that C has its own binary (see CMakeLists.txt). More...

Functions
rte_status_t	app_main_common_init (int argc, char **argv)
	Runs this process's one-time runtime setup, common to every role: unbuffered stdout, POSIX OSAdapter registration, reboot argv capture, CRC-64 init, watchdog manager init, best-effort log init, best-effort default signal handlers, and the REBOOT safe-state handler registration - see this file's own header and each step's own inline doc in app_main_common.c for why each is fatal or best-effort.

Detailed Description

Process-wide runtime setup shared by every one of this example's binaries (main.c for A/B, main_c.c for C) - OSAdapter registration, checksum/watchdog/log init, signal handlers, and the REBOOT safe-state handler. Split out so this ~70-line sequence is written once instead of duplicated across both main() entry points now that C has its own binary (see CMakeLists.txt).

Function Documentation

app_main_common_init()

rte_status_t app_main_common_init	(	int	argc,
		char **	argv )

Runs this process's one-time runtime setup, common to every role: unbuffered stdout, POSIX OSAdapter registration, reboot argv capture, CRC-64 init, watchdog manager init, best-effort log init, best-effort default signal handlers, and the REBOOT safe-state handler registration - see this file's own header and each step's own inline doc in app_main_common.c for why each is fatal or best-effort.

Parameters

argc	This process's own argc, forwarded to rte_posix_osadapter_reboot_set_argv() so a later REBOOT re-execs with the same command line.
argv	This process's own argv, same reason as argc.

Returns

RTE_STATUS_OK if every fatal step succeeded (best-effort steps only log a warning and never fail this call); the first fatal step's own failure status otherwise - the caller should print nothing further and return a non-zero exit code.
