Categories of system calls[edit]
System calls can be grouped roughly into six major categories:[1]
- Process control
- create process (for example,
forkon Unix-like systems, orNtCreateProcessin the Windows NT Native API) - Terminate process: process_mrelease(2), kill
- load, execute
- get/set process attributes
- wait for time, wait event, signal event
- allocate and free memory
- create process (for example,
- File management
- create file, delete file
- open, close
- read, write, reposition
- get/set file attributes
- Device management
- request device, release device
- read, write, reposition
- get/set device attributes
- logically attach or detach devices
- Information maintenance
- get/set total system information (including time, date, computer name, enterprise etc.)
- get/set process, file, or device metadata (including author, opener, creation time and date, etc.)
- Communication
- create, delete communication connection
- send, receive messages
- transfer status information
- attach or detach remote devices
- Protection
- get/set file permissions
