ha_ConnectDetach(), ha_ConnectDetach_r()
Detach an attached file descriptor, then close the connection
Synopsis:
#include <ha/neutrino.h>
int ha_ConnectDetach(int coid);
int ha_ConnectDetach_r(int coid);
Library:
libha
Description:
The ha_ConnectDetach() and
ha_ConnectDetach_r() functions are identical
except in the way they return errors. (For details, see the
Returns
section.)
The ha_ConnectDetach|_r() call detaches a connection (coid) that was previously attached using ha_attach(), and then closes the connection by calling the appropriate ConnectDetach|_r() call.
Returns:
The only difference between these functions is the way they indicate errors:
- ha_ConnectDetach()
- If an error occurs, -1 is returned and errno is set. Any other value returned indicates success.
- ha_ConnectDetach_r()
- EOK is returned on success. This function does NOT set errno. If an error occurs, any value from the errors returned by either the underlying ConnectDetach() call or the ha_detach() call may be returned.
Errors:
The ha_ConnectDetach|_r() call returns errors as returned by either the underlying ConnectDetach() call or the ha_detach() call.
