InternetCrackUrl
BOOL InternetCrackUrl(
    IN LPCSTR lpszUrl,
    IN DWORD dwUrlLength,
    IN DWORD dwFlags,
    IN OUT LPURL_COMPONENTS lpUrlComponents
);
Cracks a URL into its component parts.
Returns TRUE if the function succeeds, or FALSE otherwise. To get extended error information, call GetLastError.

lpszUrl
Address of a string that contains the canonical URL to crack.
dwUrlLength
Length of the lpszUrl string, or zero if lpszUrl is an ASCIIZ string.
dwFlags
Flags controlling the operation. Can be one of the following values:

ICU_DECODE Converts encoded characters back to their normal form. This can be used only if the user provides buffers in the URL_COMPONENTS structure to copy the components into.

ICU_ESCAPE Converts all escape sequences (%xx) to their corresponding characters. This can be used only if the user provides buffers in the URL_COMPONENTS structure to copy the components into.

lpUrlComponents
Address of a URL_COMPONENTS structure that receives the URL components.

The required components are indicated by members of the URL_COMPONENTS structure. Each component has a pointer to the value and has a member that stores the length of the stored value. If both the value and the length for a component are equal to zero, that component is not returned. If the pointer to the value of the component is NULL and the value of its corresponding length member is nonzero, the address of the first character of the corresponding component in the lpszUrl string is stored in the pointer, and the length of the component is stored in the length member.
If the pointer contains the address of the user-supplied buffer, the length member must contain the size of the buffer. InternetCrackUrl copies the component into the buffer, and the length member is set to the length of the copied component, minus 1 for the trailing string terminator.
For InternetCrackUrl to work properly, the size of the URL_COMPONENTS structure must be stored in the dwStructSize member.
