.Dd May 11, 2016 .Dt PR_GETRLIMIT 3PROC .Os .Sh NAME .Nm pr_getrlimit , .Nm pr_getrlimit64 .Nd inject getrlimit system call into victim process .Sh SYNOPSIS .Lb libproc n libproc.h .Ft int .Fo pr_getrlimit .Fa "struct ps_prochandle *P" .Fa "int resource" .Fa "struct rlimit *rlp" .Fc .Ft int .Fo pr_getrlimit64 .Fa "struct ps_prochandle *P" .Fa "int resource" .Fa "struct rlimit64 *rlp" .Fc .Sh DESCRIPTION The .Fn pr_getrlimit function injects the .Xr getrlimit 2 system call into the target process .Fa P by means of the agent LWP. If the process handle .Fa P is the value .Dv NULL then this will be equivalent to calling .Xr getrlimit 2 on the currently running process.

p The arguments .Fa resource and .Fa rlp have the same meaning as in .Xr getrlimit 2 . See .Xr getrlimit 2 for the full description and purpose of the .Sy getrlimit system call and its arguments.

p The .Fn 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.

p The .Fn pr_getrlimit64 function is equivalent to .Fn 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 .Xr lf64 5 for more information. .Sh RETURN VALUES Upon successful completion, the .Fn pr_getrlimit function's return value is that described in .Xr getrlimit 2 . Otherwise, .Sy -1 is returned and .Sy errno is set to .Er ENOSYS to indicate that the system call could not be injected. .Sh ERRORS For the full list of errors see the .Sy ERRORS section in .Xr getrlimit 2 .

p The .Fn pr_getrlimit function will fail if: l -tag -width Er t Er ENOSYS An error occurred while trying to invoke the agent LWP and inject a system call in the process handle .Fa P or the process handle .Fa P does not support system call injection. .El .Sh INTERFACE STABILITY .Sy Uncommitted .Sh MT-LEVEL See .Sy LOCKING in .Xr libproc 3LIB . .Sh SEE ALSO .Xr getrlimit 2 , .Xr libproc 3LIB , .Xr proc 4 , .Xr lf64 5
