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
