@CHIP-RTOS C Library - TCP/IP API

setsockopt_bsd

Set socket option.

int far setsockopt_bsd ( int sd,
                         int protocol_level,
                         int optionName,
                         const char far * optionValue,
                         int optionLength ) ;

Parameters

sd

Socket descriptor

protocol_level

One of following constants:

IP_PROTOIP_LEVEL
IP_PROTOTCP_LEVEL
SOCKET_LEVEL

optionName

Option's name constant.

optionValue

Pointer to socket option's desired value.

optionLength

Size of option data, in bytes.

Return Value

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

Comments

This API function makes it possible to manipulate options associated with a socket.

Note that the socket options of an incoming connection (using accept or accept_bsd) will be the same as the socket options of the listening socket.

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