WSPDATA structure (ws2spi.h)

  • Article

The WSPDATA structure contains service provider information.

Syntax

typedef struct WSPData {
  WORD  wVersion;
  WORD  wHighVersion;
  WCHAR szDescription[WSPDESCRIPTION_LEN + 1];
} WSPDATA, *LPWSPDATA;

Members

wVersion

Version of the Windows Sockets SPI specification that the Windows Sockets service provider expects the caller to use.

wHighVersion

Highest version of the Windows Sockets SPI specification that this service provider can support (also encoded as above). Normally this will be the same as wVersion.

szDescription[WSPDESCRIPTION_LEN + 1]

Null-terminated Unicode string into which the Windows Sockets provider copies a description of itself. The text (up to 256 characters in length) can contain any characters except control and formatting characters: the most likely use to which an SPI client will put this is to display it (possibly truncated) in a status message.

Requirements

Requirement Value
Minimum supported client Windows 2000 Professional [desktop apps only]
Minimum supported server Windows 2000 Server [desktop apps only]
Header ws2spi.h
