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

pr_setrlimit, pr_setrlimit64inject setrlimit system call into victim process

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

pr_setrlimit64(struct ps_prochandle *P, int resource, struct rlimit64 *rlp);

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

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

The () 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 () function is equivalent to pr_setrlimit(); 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.

Upon successful completion, the pr_setrlimit() function's return value is that described in setrlimit(2). Otherwise, is returned and 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 setrlimit(2).

The pr_setrlimit() function will fail if:

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.

See in libproc(3LIB).
