Function setrlimit

pub fn setrlimit(
    resource: Resource,
    soft_limit: rlim_t,
    hard_limit: rlim_t,
) -> Result<()>

Set the current processes resource limits

Parameters

• resource: The Resource that we want to set the limits of.
• soft_limit: The value that the kernel enforces for the corresponding resource.
• hard_limit: The ceiling for the soft limit. Must be lower or equal to the current hard limit for non-root users.

The special value RLIM_INFINITY indicates that no limit will be enforced.

Examples

let soft_limit = 512;
let hard_limit = 1024;
setrlimit(Resource::RLIMIT_NOFILE, soft_limit, hard_limit).unwrap();
