ios - What are the 0x3F 0xB3 bytes for in /dev/fsevents? -


i experimenting filemon source code. i'm debugging why crashes on ios 7. not have experience in fsevents noticed in bytestream read off of /dev/fsevents follows pattern:

(fileop info) (args) 0x3f 0xb3 (fileop info) (args)

where arg in (args) follow format:

(arg id) (arg len) (arg value)

what 0x3f 0xb3 for? guess means 0xbeef? correct assume sentinel separate different file operation info in /dev/fsevents?

from header file:

#define fse_arg_done     0xb33f   // no more arguments

so, yes, it's used sentinel.
