Show all headers | View raw

From: Arnaldo Carvalho de Melo <acme@redhat.com>

Showing the COMM for that return, if available.

  # trace -e getpid,getppid,set_tid_address
    490.007 ( 0.005 ms): sh/8250 getpid(...) = 8250 (sh)
    490.014 ( 0.001 ms): sh/8250 getppid(...) = 7886 (make)
    491.156 ( 0.004 ms): install/8251 set_tid_address(tidptr: 0x7f204a9d4ad0) = 8251 (install)
