io_openfd()

int io_openfd (resmgr_context_t *ctp,
               io_openfd_t *msg,
               RESMGR_OCB_T *ocb ) 

Classification: I/O

Default handler: iofunc_openfd_default()

Helper functions: iofunc_ability_check(), iofunc_openfd()

Client function: openfd()

Messages: _IO_OPENFD

Data structure:

struct _io_openfd {
  uint16_t            type;
  uint16_t            combine_len;
  uint32_t            ioflag;
  uint16_t            sflag;
  uint16_t            reserved1;
  struct _msg_info32  info;
  uint32_t            reserved2;
  uint32_t            key;
};

typedef union {
  struct _io_openfd i;
} io_openfd_t;

Description: This function is similar to the handler provided for io_open(), except that instead of a pathname, an already-open file descriptor is passed (by virtue of passing you the ocb in the function call).

Returns: The status via the helper macro _RESMGR_STATUS().
