WSAStartup

The first call to WSAStartup initiates the use of eRTOS TCP/IP stack by a process. Subsequent calls to WSAStartup increment a startup count. An application must perform an equal number of WSACleanup calls, which would decrement a startup count. The final call performs an actual cleanup.

Syntax

int WSAStartup(
    WORD wVersionRequested,
    LPWSADATA lpWSAData
);

Parameters

wVersionRequested

The highest version of WinSock support that the caller can use.  The high order byte specifies the minor version (revision) number; the low-order byte specifies the major version number.

lpWSAData

A pointer to the WSADATA data structure that is to receive details of the WinSock implementation.

Return Value

If the function succeeds, it returns 0 (zero).

If the function fails, it returns one of these error codes:

Remarks

The WSAStartup function should only be called once within a process.
