NAME

tnfctl_close - close a tnfctl handle

SYNOPSIS

cc [ flag ... ] file ... -ltnfctl [ library ... ]
#include <tnf/tnfctl.h> 
tnfctl_errcode_t tnfctl_close(tnfctl_handle_t *hndl,
    tnfctl_targ_op_t action);

DESCRIPTION

tnfctl_close() is used to close a tnfctl handle and to free up the memory associated with the handle. When the handle is closed, the tracing state and the states of the probes are not changed. tnfctl_close() can be used to close handles in any mode, that is, whether they were created by tnfctl_internal_open(3TNF), tnfctl_pid_open(3TNF), tnfctl_exec_open(3TNF), tnfctl_indirect_open(3TNF), or tnfctl_kernel_open(3TNF).

The action argument is only used in direct mode, that is, if hndl was created by tnfctl_exec_open(3TNF) or tnfctl_pid_open(3TNF). In direct mode, action specifies whether the process will proceed, be killed, or remain suspended. action may have the following values:

TNFCTL_TARG_DEFAULT

: Kills the target process if hndl was created with tnfctl_exec_open(3TNF), but lets it continue if it was created with tnfctl_pid_open(3TNF).

TNFCTL_TARG_KILL

: Kills the target process.

TNFCTL_TARG_RESUME

: Allows the target process to continue.

TNFCTL_TARG_SUSPEND

: Leaves the target process suspended. This is not a job control suspend. It is possible to attach to the process again with a debugger or with the tnfctl_pid_open(3TNF) interface. The target process can also be continued with prun(1).
