NAME

rtapi_app_main - User-provided function to initialize a component

SYNTAX

#include <rtapi_app.h>
int rtapi_app_main(void);

ARGUMENTS

None

DESCRIPTION

The body of rtapi_app_main, which is provided by the component author, generally consists of a call to rtapi_init or hal_init, followed by other component-specific initialization code.

RETURN VALUE

Return 0 for success. Return a negative errno value (e.g., -EINVAL) on error. Existing code also returns RTAPI or HAL error values, but using negative errno values gives better diagnostics from insmod.

REALTIME CONSIDERATIONS

Called automatically by the rtapi infrastructure in an initialization (not realtime) context.
