The pr_setrlimit() 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 setrlimit system call and its arguments.
The pr_setrlimit() 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_setrlimit64() 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, -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 setrlimit(2).
The pr_setrlimit() 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.

ERRORS
