|
|
* The write side of the prlimit64 ABI: (pid = 0, resource,
|
|
* new_limit = &rlim, old_limit = NULL). struct rlimit is the kernel's
|
|
* struct rlimit64 layout on x86_64, so the record passes through without
|
|
* conversion; the kernel rejects a soft limit above the hard limit with
|
|
* EINVAL and a hard-limit raise without CAP_SYS_RESOURCE with EPERM.
|
|
*
|
|
* setrlimit64 is a name-only distinction on this architecture (rlim_t is
|
|
* already 64 bits); it exists as a separate exported symbol for LFS
|
|
* callers.
