Expand description

Types of process resources.

The Resource enum is platform dependent. Check different platform manuals for more details. Some platform links have been provided for easier reference (non-exhaustive).

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

RLIMIT_AS = 9

The maximum amount (in bytes) of virtual memory the process is allowed to map.

§

RLIMIT_CORE = 4

The largest size (in bytes) core(5) file that may be created.

§

RLIMIT_CPU = 0

The maximum amount of cpu time (in seconds) to be used by each process.

§

RLIMIT_DATA = 2

The maximum size (in bytes) of the data segment for a process

§

RLIMIT_FSIZE = 1

The largest size (in bytes) file that may be created.

§

RLIMIT_NOFILE = 7

The maximum number of open files for this process.

§

RLIMIT_STACK = 3

The maximum size (in bytes) of the stack segment for a process.

§

RLIMIT_LOCKS = 10

A limit on the combined number of flock locks and fcntl leases that this process may establish.

§

RLIMIT_MEMLOCK = 8

The maximum size (in bytes) which a process may lock into memory using the mlock(2) system call.

§

RLIMIT_MSGQUEUE = 12

A limit on the number of bytes that can be allocated for POSIX message queues for the real user ID of the calling process.

§

RLIMIT_NICE = 13

A ceiling to which the process’s nice value can be raised using setpriority or nice.

§

RLIMIT_NPROC = 6

The maximum number of simultaneous processes for this user id.

§

RLIMIT_RSS = 5

When there is memory pressure and swap is available, prioritize eviction of a process’ resident pages beyond this amount (in bytes).

§

RLIMIT_RTPRIO = 14

A ceiling on the real-time priority that may be set for this process using sched_setscheduler and sched_set‐ param.

§

RLIMIT_RTTIME = 15

A limit (in microseconds) on the amount of CPU time that a process scheduled under a real-time scheduling policy may con‐ sume without making a blocking system call.

§

RLIMIT_SIGPENDING = 11

A limit on the number of signals that may be queued for the real user ID of the calling process.
