proc uname(): Uname {...}{.raises: [OSError], tags: [].}
-
Provides system information in a Uname struct with sysname, nodename, release, version and machine attributes.
Example:
echo uname().nodename, uname().release, uname().version doAssert uname().sysname.len != 0
Source Edit proc fsync(fd: int) {...}{.raises: [OSError], tags: [].}
- synchronize a file's buffer cache to the storage device Source Edit
proc stat(path: string): Stat {...}{.raises: [OSError], tags: [].}
- Returns file status in a Stat structure Source Edit
proc memoryLock(a1: pointer; a2: int) {...}{.raises: [OSError], tags: [].}
- Locks pages starting from a1 for a1 bytes and prevent them from being swapped. Source Edit
proc memoryLockAll(flags: int) {...}{.raises: [OSError], tags: [].}
-
Locks all memory for the running process to prevent swapping.
example:
memoryLockAll(MCL_CURRENT or MCL_FUTURE)
Source Edit proc memoryUnlock(a1: pointer; a2: int) {...}{.raises: [OSError], tags: [].}
- Unlock pages starting from a1 for a1 bytes and allow them to be swapped. Source Edit
proc memoryUnlockAll() {...}{.raises: [OSError], tags: [].}
- Unlocks all memory for the running process to allow swapping. Source Edit
proc sendSignal(pid: Pid; signal: int) {...}{.raises: [OSError], tags: [].}
- Sends a signal to a running process by calling kill. Raise exception in case of failure e.g. process not running. Source Edit
proc mkstemp(prefix: string; suffix = ""): (string, File) {...}{.raises: [OSError], tags: [].}
- Creates a unique temporary file from a prefix string. A six-character string will be added. If suffix is provided it will be added to the string The file is created with perms 0600. Returns the filename and a file opened in r/w mode. Source Edit
proc mkdtemp(prefix: string): string {...}{.raises: [OSError], tags: [].}
- Creates a unique temporary directory from a prefix string. Adds a six chars suffix. The directory is created with permissions 0700. Returns the directory name. Source Edit
