Berkeley Sockets/iX Reference Manual

CLOSE, SCLOSE 


NOTE  This routine is called sclose for non-POSIX users, and is called
      close for POSIX users.


C Interface 

         int close (s)
         int s;

         int sclose (s)
         int s;

Description 

Closes the socket descriptor indicated by s.  If this file descriptor is
the last reference to the socket, then it is deactivated.  For example,
on the last close of a socket, associated naming information and queued
data are discarded.

The SO_LINGER option of setsockopt can be used to determine what happens
to data queued at the time of the close.

For more information about close or any other POSIX function, refer to
the MPE/iX Developer's Kit Reference Manual, Volume 1.

Return Value 

If the call completes successfully, a value of 0 is returned.  If the
call is unsuccessful, a value of -1 is returned and errno is set to
indicate the error.

Errors 

The following error is returned by close:

[EBADF]               The argument s is not a valid descriptor.
