@CHIP-RTOS C Library - TCP/IP API

close_bsd

Close a socket.

int far close_bsd ( int sd) ;

Parameters

sd

Socket descriptor

Return Value

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

Comments

Closes the socket indicated by sd and releases all of its associated resources.

The parameters to close_bsd() are identical to the parameters of the BSD4.4 close() socket function.

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 closesocket() call can be used in BSD 4.4 compatible style with the parameters specified above.   Using this switch the CLIB TCPIP_Socket.H redefines closesocket() to close_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.
