Expand description

Represents system call numbers used in project2

Each variant corresponds to a specific system call that can be invoked using the system call interface. The numeric values align with the syscall table in the operating system.

Variants§

Exit = 0

Terminates the calling process.

Open = 1

Opens a file and returns a file descriptor.

Read = 2

Reads data from a file descriptor.

Write = 3

Writes data to a file descriptor.

Seek = 4

Moves the file offset of an open file.

Tell = 5

Retrieves the current file offset.

Close = 6

Closes an open file descriptor.

Pipe = 7

Create an interprocess communication channel.

Mmap = 8

Map the memory.

Munmap = 9

Unmap the memory.
