pr_fstatvfs
—
inject fstatvfs system call into victim process
Process Control Library (libproc, -lproc)
#include
<libproc.h>
int
pr_fstatvfs
(struct ps_prochandle
*P, int fd, statvfs_t
*buf);
The
pr_fstatvfs
()
function injects the fstatvfs(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
fstatvfs(2) on the currently running
process.
The arguments fd and buf have the same meaning as in fstatvfs(2). See fstatvfs(2) for the full description and purpose of the fstatvfs system call and its arguments.
The
pr_fstatvfs
()
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_fstatvfs
() function's return value is that
described in fstatvfs(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 fstatvfs(2).
The pr_fstatvfs
() function will fail
if:
ENOSYS
See LOCKING in libproc(3LIB).
