pr_statvfs —
inject statvfs system call into victim process
Process Control Library (libproc, -lproc)
#include
<libproc.h>
int
pr_statvfs(struct ps_prochandle
*P, const char *path, statvfs_t
*buf);
The
pr_statvfs()
function injects the statvfs(2)
system call into the target process P by means of the
agent LWP. If the process handle P is the value
NULL then this will be equivalent to calling
statvfs(2) on the currently running
process.
The arguments path and buf have the same meaning as in statvfs(2). See statvfs(2) for the full description and purpose of the statvfs system call and its arguments.
The
pr_statvfs()
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_statvfs() function's return value is that
described in statvfs(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 statvfs(2).
The pr_statvfs() function will fail
if:
ENOSYSSee LOCKING in libproc(3LIB).
