Trace Hook IDs: 253 through 25A

The following trace hook IDs are stored in the /usr/include/sys/trchkid.h file.

253 : HKWD SOCKET

This hook ID records TCP/IP socket layer events. TCP/IP socket layer events are recorded by socket-layer code, most of which records parameters passed to functions and return values from functions.

sobind (value, value)

solisten (value, value)

sofree (value)

soclose (value)

return from soclose (value)

soaccept (value, value, value, value)

return from soaccept (value)

return from sodisconnect (value)

sosend (value, value, value, value, value)

return from sosend (value)

return from soreceive (value, value)

soshutdown (value)

sorflush (value, value, value, value)

sosetopt (value)

return from sosetopt (value, value, value, value)

sogetopt (value, value, value, value)

return from sogetopt

sohasoutofband (value)

return from sohasoutofband

254 : HKWD MBUF
