Function Documentation

int fdesc_add (  int  d, resid_t  resid, int  statusfl, int  fl )

add a fd

void fdesc_cache_add (  int  fd, t_fshare *  fshare, int  refcnt )

void fdesc_cache_dump (  void   )

int fdesc_cache_get (  int  fd, t_fshare *  fshare, int *  refcnt )

void fdesc_cache_invalidate (  void   )

void fdesc_dump (  void   )

dump local table (debug)

int fdesc_get (  int  d, u_int32_t  fdescopts, t_fdesc **  fdesc, t_fshare *  fshare, int *  refcnt, char *  s )

get full fd information

t_fdesc* fdesc_get_i (  int  fd  )

void fdesc_init (  void   )

initializes local fd table

int fdesc_nextd (  int  from  )

get next free descriptor

int fdesc_rm (  t_fdesc *  fdesc, t_fshare *  fshare, int  refcnt )

removes a fd - refcnt should be theorical refcnt

int fshare_add (  resid_t *  resid, int  gate, int  gate_id, mode_t  perm )

add a fshare struct

int fshare_get (  resid_t  resid, t_fshare *  fshare, int *  refcnt )

get fshare struct associated to resid

int fshare_rm (  resid_t  resid  )

remove a fshare struct
