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