pr_close — inject
close system call into victim process
Process Control Library (libproc, -lproc)
#include
<libproc.h>
int
pr_close(struct ps_prochandle
*P, int fd);
The
pr_close()
function injects the close(2) system
call into the target process P by means of the agent
LWP. If the process handle P is
NULL then this is equivalent to calling
close(2) on the currently running
process.
The argument fd has the same meaning as in close(2). See close(2) for the full description and purpose of the close system call and its arguments.
The
pr_close()
function only works on active processes. Process handles that correspond to
core files, zombie processes, or ELF objects do not support system call
injection.
Upon successful completion, the pr_close()
function's return value is that described in
close(2). Otherwise,
-1 is returned
and
errno is
set to ENOSYS to indicate that the system call could
not be injected.
For the full list of errors see the ERRORS section in close(2).
The pr_close() function will fail if:
ENOSYSSee LOCKING in libproc(3LIB).
