Detailed Description

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 65 of file app-layer-parser.h.

◆ APP_LAYER_INCOMPLETE

#define APP_LAYER_INCOMPLETE (   c,
 
)    (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 73 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.
