setsockopt() in System Libraries STDLIB

IMPORT_C int setsockopt(int, int, int, void *, size_t);

Description

`int`	Identifies whether the operation applies to the socket itself or to the underlying protocol being used. The socket itself is identified by the symbolic constant SOL_SOCKET. Other protocol levels require the protocol number for the appropriate protocol controlling the option.
`int`	Specifies a single option to which the request applies, negative option values are not support on Symbian OS.
`void *`	Specifies a value for the option.
`size_t`	Specifies the length of the option value.
