VOP_ALLOCATE(9)

This call allocates storage for a range of offsets in a file.  It
is used to implement the system call.  Its arguments are: The vn‐
ode  of the file.  The start of the range to allocate storage for
in the file.  The length of the range to allocate storage for  in
the  file.   The and arguments are updated to reflect the portion
of the range that still needs to be allocated on return.  A  par‐
tial allocation is considered a successful operation.  The file's
contents  are not changed.  The file should be exclusively locked
on entry and will still be locked on exit.  Zero is  returned  if
the  call  is  successful, otherwise an appropriate error code is
returned.  An attempt was made to write a file that  exceeds  the
process's  file  size  limit  or the maximum file size.  The file
system is full.  An append-only flag is set on the file, but  the
caller is attempting to write before the current end of file.
