NSP_ROUTINE structure (ws2spi.h)
The NSP_ROUTINE structure contains information regarding the functions implemented by a namespace service provider version 1 (NSPv1) provider.
Syntax
typedef struct _NSP_ROUTINE {
DWORD cbSize;
DWORD dwMajorVersion;
DWORD dwMinorVersion;
LPNSPCLEANUP NSPCleanup;
LPNSPLOOKUPSERVICEBEGIN NSPLookupServiceBegin;
LPNSPLOOKUPSERVICENEXT NSPLookupServiceNext;
LPNSPLOOKUPSERVICEEND NSPLookupServiceEnd;
LPNSPSETSERVICE NSPSetService;
LPNSPINSTALLSERVICECLASS NSPInstallServiceClass;
LPNSPREMOVESERVICECLASS NSPRemoveServiceClass;
LPNSPGETSERVICECLASSINFO NSPGetServiceClassInfo;
LPNSPIOCTL NSPIoctl;
} NSP_ROUTINE, *LPNSP_ROUTINE;
Members
cbSize
Type: DWORD
The size, in bytes, of the structure. Note that the size of the NSP_ROUTINE structure changed on Windows XP and later.
dwMajorVersion
Type: DWORD
The major version of the service provider specification supported by this provider.
dwMinorVersion
Type: DWORD
The minor version of the service provider specification supported by this provider.
NSPCleanup
Type: LPNSPCLEANUP
A pointer to the NSPCleanup function implemented by the namespace provider. Every NSP function entry must point to a valid function. If the provider does not implement this function, the NSPCleanup function should return WSAEOPNOTSUPP.
NSPLookupServiceBegin
Type: LPNSPLOOKUPSERVICEBEGIN
A pointer to the NSPLookupServiceBegin function implemented by the namespace provider. Every NSP function entry must point to a valid function. If the provider does not implement this function, the NSPLookupServiceBegin function should return WSAEOPNOTSUPP.
NSPLookupServiceNext
Type: LPNSPLOOKUPSERVICENEXT
A pointer to the NSPLookupServiceNext function implemented by the namespace provider. Every NSP function entry must point to a valid function. If the provider does not implement this function, the NSPLookupServiceNext function should return WSAEOPNOTSUPP.
NSPLookupServiceEnd
Type: LPNSPLOOKUPSERVICEEND
A pointer to the NSPLookupServiceEnd function implemented by the namespace provider. Every NSP function entry must point to a valid function. If the provider does not implement this function, the NSPLookupServiceEnd function should return WSAEOPNOTSUPP.
NSPSetService
Type: LPNSPSETSERVICE
A pointer to the NSPSetService function implemented by the namespace provider. Every NSP function entry must point to a valid function. If the provider does not implement this function, the NSPSetService function should return WSAEOPNOTSUPP.
NSPInstallServiceClass
Type: LPNSPINSTALLSERVICECLASS
A pointer to the NSPInstallServiceClass function implemented by the namespace provider. Every NSP function entry must point to a valid function. If the provider does not implement this function, the NSPInstallServiceClass function should return WSAEOPNOTSUPP.
NSPRemoveServiceClass
Type: LPNSPREMOVESERVICECLASS
A pointer to the NSPRemoveServiceClass function implemented by the namespace provider. Every NSP function entry must point to a valid function. If the provider does not implement this function, the NSPRemoveServiceClass function should return WSAEOPNOTSUPP.
NSPGetServiceClassInfo
Type: LPNSPGETSERVICECLASSINFO
A pointer to the NSPGetServiceClassInfo function implemented by the namespace provider. Every NSP function entry must point to a valid function. If the provider does not implement this function, the NSPGetServiceClassInfo function should return WSAEOPNOTSUPP.
NSPIoctl
Type: LPNSPIOCTL
A pointer to the NSPIoctl function implemented by the namespace provider. Every NSP function entry must point to a valid function. If the provider does not implement this function, the NSPIoctl function should return WSAEOPNOTSUPP.
Remarks
The size of the NSP_ROUTINE structure changed on Windows XP and later. The cbSize member should be used to determine which version of the NSP_ROUTINE structure is being used.
The version of the NSP_ROUTINE structure on Windows XP and later has the following new member added: NSPIoctl.
