@CHIP-RTOS C Library - TCP/IP API

shutdown_bsd

Shutdown TCP socket

int far shutdown_bsd(int sd, int dir);

Parameters

sd

Socket descriptor

dir

Direction:   0=Read, 1=write, 2=both

Return Value

0 on success
-1: Failure, error code is available using get_socketerror() API.

Comments

Shutdown a socket in read, write or both directions.   This API function only works on TCP sockets.

If the compilation switch

     #define BSD44_SOCKET_API_STYLE

is set as a global define in the user application prior to including the Beck C-library header files, the shutdown() call can be used in BSD 4.4 compatible style with the parameters specified above.   Using this switch the CLIB TCPIP_Socket.H redefines shutdown() to shutdown_bsd() .

RTOS API

On the first call, this library function invokes a software interrupt which modifies the code at the calling site inside your application program.   A direct FAR JMP into the @CHIP-RTOS-x86 implementation for this function is installed so that on return and on any subsequent calls to this API this dynamic link reaches the function's implementation directly.
