Functions

chdir	Change the process's working directory
chmod	Deprecated
clock_gettime	Get the current system time
clone⚠	Produce a fork of the current process, or a new process thread
close	Close a file
dup	Copy and transform a file descriptor
dup2	Copy and transform a file descriptor
exit	Exit the current process
fchmod	Change file permissions
fchown	Change file ownership
fcntl	Change file descriptor flags
fexec	Replace the current process with a new executable
fmap⚠	Map a file into memory, but with the ability to set the address to map into, either as a hint or as a requirement of the map.
fpath	Retrieve the canonical path of a file
frename	Rename a file
fstat	Get metadata about a file
fstatvfs	Get metadata about a filesystem
fsync	Sync a file descriptor to its underlying medium
ftruncate	Truncate or extend a file to a specified length
funmap⚠	Unmap whole (or partial) continous memory-mapped files
futex⚠	Fast userspace mutex
futimens
getcwd	Get the current working directory
getegid	Get the effective group ID
getens	Get the effective namespace
geteuid	Get the effective user ID
getgid	Get the current group ID
getns	Get the current namespace
getpgid	Get the process group ID
getpid	Get the current process ID
getppid	Get the parent process ID
getuid	Get the current user ID
iopl⚠	Set the I/O privilege level
kill	Send a signal sig to the process identified by pid
link⚠	Create a link to a file
lseek	Seek to offset bytes in a file descriptor
mkns	Make a new scheme namespace
mprotect⚠	Change mapping flags
nanosleep	Sleep for the time specified in req
open	Open a file
physalloc⚠	Allocate frames, linearly in physical memory.
physalloc2⚠	Allocate frames, linearly in physical memory, with an extra set of flags. If the flags contain PARTIAL_ALLOC, this will result in physalloc3 with min = 1.
physalloc3⚠	Allocate frames, linearly in physical memory, with an extra set of flags. If the flags contain PARTIAL_ALLOC, the min parameter specifies the number of frames that have to be allocated for this operation to succeed. The return value is the offset of the first frame, and min is overwritten with the number of frames actually allocated.
physfree⚠	Free physically allocated pages
physmap⚠	Map physical memory to virtual memory
physunmap⚠	Unmap previously mapped physical memory
pipe2	Create a pair of file descriptors referencing the read and write ends of a pipe
read	Read from a file descriptor into a buffer
rmdir	Remove a directory
sched_yield	Yield the process's time slice to the kernel
setpgid	Set the process group ID
setregid	Set the current process group IDs
setrens	Make a new scheme namespace
setreuid	Set the current process user IDs
sigaction	Set up a signal handler
sigprocmask	Get and/or set signal masks
sigreturn
umask	Set the file mode creation mask
unlink	Remove a file
virttophys⚠	Convert a virtual address to a physical one
waitpid	Check if a child process has exited or received a signal
write	Write a buffer to a file descriptor
