PR_GETRLIMIT(3PROC) Process Control Library Functions PR_GETRLIMIT(3PROC)

NAME

pr_getrlimit, pr_getrlimit64 - inject getrlimit system call into victim
process

LIBRARY

Process Control Library (libproc, -lproc)

SYNOPSIS

#include <libproc.h>

int
pr_getrlimit(struct ps_prochandle *P, int resource,
struct rlimit *rlp);

int
pr_getrlimit64(struct ps_prochandle *P, int resource,
struct rlimit64 *rlp);

DESCRIPTION

The pr_getrlimit() function injects the getrlimit(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
getrlimit(2) on the currently running process.

The arguments resource and rlp have the same meaning as in
getrlimit(2). See getrlimit(2) for the full description and purpose of
the getrlimit system call and its arguments.

The pr_getrlimit() function only works on active processes. Process
handles that correspond to core files, zombie processes, or ELF objects
do not support system call injection.

The pr_getrlimit64() function is equivalent to pr_getrlimit(); however,
rather than having the rlimit information be subject to the data model
of the target process, they always provide 64-bit rlimit information.
See lf64(7) for more information.

RETURN VALUES

Upon successful completion, the pr_getrlimit() function's return value
is that described in getrlimit(2). Otherwise, -1 is returned and errno
is set to ENOSYS to indicate that the system call could not be
injected.

ERRORS

For the full list of errors see the ERRORS section in getrlimit(2).

The pr_getrlimit() 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
or the process handle P does not support system call
injection.
