URL_COMPONENTS Structure

---

Contains the constituent parts of a URL. This structure is used with the InternetCrackUrl and InternetCreateUrl functions.

Syntax

typedef struct {
    DWORD dwStructSize;
    LPTSTR lpszScheme;
    DWORD dwSchemeLength;
    INTERNET_SCHEME nScheme;
    LPTSTR lpszHostName;
    DWORD dwHostNameLength;
    INTERNET_PORT nPort;
    LPTSTR lpszUserName;
    DWORD dwUserNameLength;
    LPTSTR lpszPassword;
    DWORD dwPasswordLength;
    LPTSTR lpszUrlPath;
    DWORD dwUrlPathLength;
    LPTSTR lpszExtraInfo;
    DWORD dwExtraInfoLength;
} URL_COMPONENTS, *LPURL_COMPONENTS;

The actual syntax of this structure varies between its ANSI and Unicode implementations. For more information, see Win32 Internet Functions Syntax.

Members

dwStructSize

Unsigned long integer value that contains the size, in TCHAR, of this structure. Used for version checking. The size of this structure must be set to initialize this structure properly.

lpszScheme

Address of a string value that contains the scheme name.

dwSchemeLength

Unsigned long integer value that contains the length of the scheme name in TCHAR.

nScheme

INTERNET_SCHEME value that indicates the Internet protocol scheme.

lpszHostName

Address of a string value that contains the host name.

dwHostNameLength

Unsigned long integer value that contains the length of the host name in TCHAR.

nPort

Converted port number.

lpszUserName

Address of a string value that contains the user name.

dwUserNameLength

Unsigned long integer value that contains the length of the user name in TCHAR.

lpszPassword

Address of a string value that contains the password.

dwPasswordLength

Unsigned long integer value that contains the length of the password in TCHAR.

lpszUrlPath

Address of a string value that contains the URL path.

dwUrlPathLength

Unsigned long integer value that contains the length of the URL path in TCHAR.

lpszExtraInfo

Address of a string value that contains the extra information (for example, ?something or #something).

dwExtraInfoLength

Unsigned long integer value that contains the length of the extra information in TCHAR.

Remarks

For InternetCrackUrl, if a pointer member and its corresponding length member are both zero, that component is not returned. If the pointer member is NULL but the length member is not zero, both the pointer and length members are returned. If both pointer and corresponding length members are nonzero, the pointer member points to a buffer where the component is copied. The component can be un-escaped, depending on the dwFlags parameter of InternetCrackUrl.

For InternetCreateUrl, the pointer members should be NULL if the component is not required. If the corresponding length member is zero, the pointer member is the address of a zero-terminated string. If the length member is not zero, it is the string length of the corresponding pointer member.
