Macro Definition Documentation

◆ APP_LAYER_ERROR

#define APP_LAYER_ERROR (AppLayerResult) { -1, 0, 0 }

parser has hit an unrecoverable error. Returning this to the API leads to no further calls to the parser.

Definition at line 60 of file app-layer-parser.h.

◆ APP_LAYER_INCOMPLETE

#define APP_LAYER_INCOMPLETE	(	c,
		n
	)	(AppLayerResult) { 1, (c), (n) }

parser needs more data. Through 'c' it will indicate how many of the input bytes it has consumed. Through 'n' it will indicate how many more bytes it needs before getting called again.

Note: consumed (c) should never be more than the input len needed (n) + consumed (c) should be more than the input len

Definition at line 68 of file app-layer-parser.h.

◆ APP_LAYER_OK

#define APP_LAYER_OK (AppLayerResult) { 0, 0, 0 }

parser has successfully processed in the input, and has consumed all of it.

Definition at line 56 of file app-layer-parser.h.

Definition at line 42 of file app-layer-parser.h.

◆ APP_LAYER_TX_INSPECTED_FLAG

#define APP_LAYER_TX_INSPECTED_FLAG BIT_U64(63)

is tx fully inspected?

Definition at line 49 of file app-layer-parser.h.

◆ APP_LAYER_TX_PREFILTER_MASK

#define APP_LAYER_TX_PREFILTER_MASK ~APP_LAYER_TX_INSPECTED_FLAG

other 63 bits are for tracking which prefilter engine is already completely inspected
