PR_STATVFS(3PROC) Process Control Library Functions PR_STATVFS(3PROC)
- 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
() function injects the statvfs(2)
system call into the
target process P
by means of the agent LWP. If the process handle P
value NULL then this will be equivalent to calling statvfs(2)
currently running process.
The arguments path
have the same meaning as in statvfs(2)
. See statvfs(2)
for the full description and purpose of the statvfs
and its arguments.
() 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
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)
() function will fail if:
ENOSYS An error occurred while trying to invoke the agent LWP
and inject a system call in the process handle P
process handle P
does not support system call injection.
