vn_closefile(fp,
l)vn_closefile() simply calls
vn_close(9) with the
appropriate arguments.vn_fcntl(fp,
com, data,
l)vn_fcntl() simply locks the vnode and invokes the
vnode operation
VOP_FCNTL(9) with the
command com and buffer data.
The vnode is unlocked on return. If the operation is successful zero is
returned, otherwise an appropriate error is returned.vn_ioctl(fp,
com, data,
l)vn_ioctl() simply locks the vnode and
invokes the vnode operation
VOP_IOCTL(9) with the
command com and buffer data.
The vnode is unlocked on return. If the operation is successful zero is
returned, otherwise an appropriate error is returned.vn_read(fp,
offset, uio,
cred, flags)vn_poll(fp,
events, l)vn_poll() simply calls
VOP_POLL(9) with the
events events and the calling lwp
l. The function returns a bitmask of available
events.vn_statfile(fp,
sb, l)vn_statfile() basically calls the vnode operation
VOP_GETATTR(9) and
transfer the contents of a vattr structure into a struct stat. If the
operation is successful zero is returned, otherwise an appropriate error
code is returned.vn_write(fp,
