-.Os
-.Sh NAME
-.Nm getentropy
-.Nd fill a buffer with high quality random data
-.Sh LIBRARY
-.Lb libc
-.Sh SYNOPSIS
-.In unistd.h
-.Ft int
-.Fn getentropy "void *buf" "size_t buflen"
-.Sh DESCRIPTION
-The
-.Fn getentropy
-function fills a buffer with high quality random data, suitable for seeding
-cryptographically secure pseudo-random number generators.
-.Pp
-.Fn getentropy
-is only intended for seeding random number generators and is not intended
-for use by regular code which simply needs secure random data.
-For this purpose, please use
-.Xr arc4random 3 .
-.Pp
-The maximum value for
-.Li buflen
-is 256 bytes.
-.Sh IMPLEMENTATION NOTES
-.Fn getentropy
-reads from the
-.Xr sysctl 7
-variable
-.Li kern.arandom .
-.Sh RETURN VALUES
-The
-.Fn getentropy
-function returns 0 on success, and \-1 if an error occurred.
-.Sh ERRORS
-.Fn getentropy
-will succeed unless:
-.Bl -tag -width Er
-.It Bq Er EFAULT
-The
-.Fa buf
-argument points to an invalid memory address.
-.It Bq Er EIO
-Too many bytes were requested.
-.El
-.Sh SEE ALSO
-.Xr arc4random 3 ,
-.Xr rnd 4
-.Sh STANDARDS
-The
-.Fn getentropy
-function is non-standard.
-.Sh HISTORY
-The
-.Fn getentropy
-function first appeared in
-.Ox 5.6 ,
-then in
-.Fx 12.0 ,
-and
-.Nx 10 .
