|
// search isnt very good. add a 1-element MRU cache. even for the most common
|
|
// (by far) case of "http" (0th entry), we *still* win due to the cheaper
|
|
// StrCmpC and skipped loop.

Probes a buffer for writeability. Used as part of API parameter validation,

this function tests the first and last locations in a buffer. This is not

as strict as the IsBadXPtr() Windows APIs, but it means we don't have to

test every location in the buffer

Arguments:
|
|
|
|
lpBuffer - pointer to buffer to test
|

|
|
dwBufferLength - length of buffer

Return Value:

DWORD

Success - ERROR_SUCCESS

Routine Description:

This function extracts any and all parts of the address information for a
|
|
generic URL. If any of the address parts contain escaped characters (%nn)
|
|
then they are converted in situ
|
|
|
|
The generic addressing format (RFC 1738) is:
|
|
|
|
<user>:<password>@<host>:<port>
|
|
|
|
The addressing information cannot contain a password without a user name,
|
|
or a port without a host name
|
|
NB: ftp://ftp.microsoft.com uses URL's that have a port without a host name!
|
|
(e.g. http://:0/-http-gw-internal-/menu.gif)
|
|
|
|
Although only the lpszUrl and lpdwUrlLength fields are required, the address
|
|
parts will be checked for presence and completeness
|
|
|
|
Assumes: 1. If one of the optional lpsz fields is present (e.g. lpszUserName)
|
|
then the accompanying lpdw field must also be supplied

Arguments:

|
|
OUT: URL remaining after address information
|

N.B. The url-path is NOT canonicalized (unescaped)

|
|
which must be parsed out by the protocol-specific
|
|
parser
|
|
|
|
lpdwUrlLength - returned length of the remainder of the URL after the
|
|
address information
|
|
|
|
lpszUserName - returned pointer to the user name
|
|
This parameter can be omitted by those protocol parsers
|
|
that do not require or expect user names in the URL
|
|
|
|
lpdwUserNameLength - returned length of the user name part
|
|
This parameter can be omitted by those protocol parsers
|
|
that do not require or expect user names in the URL
|
|
|
|
lpszPassword - returned pointer to the password
|
|
This parameter can be omitted by those protocol parsers
|
|
that do not require or expect user passwords in the URL
|
|
|
|
lpdwPasswordLength - returned length of the password
|
|
This parameter can be omitted by those protocol parsers
|
|
that do not require or expect user passwords in the URL
|
|
|
|
lpszHostName - returned pointer to the host name
|

This parameter can be omitted by those protocol parsers
|
|
that do not require the host name info
|
|
|
|
lpdwHostNameLength - returned length of the host name
|
|
This parameter can be omitted by those protocol parsers

lpPort - returned value of the port field

This parameter can be omitted by those protocol parsers

lpPort parameter is omitted.

OVERWRITTEN if it contains escape sequences that
|
|
we will convert back to ANSI characters
|
|
|
|
dwUrlLength - if not 0, string length of lpszUrl
|
|
|
|
bEscape - TRUE if we are to escape the url-path
|
|
|
|
lpSchemeType - returned scheme type - e.g. INTERNET_SCHEME_HTTP
|
|
|
|
lpszSchemeName - returned scheme name
|
|
|
|
lpdwSchemeNameLength - length of scheme name
|
|
|
|
lpszHostName - returned host name
|
|
|
|
lpdwHostNameLength - length of host name buffer
|
|
|
|
lpServerPort - returned server port if present in the URL, else 0
|
|
|
|
lpszUserName - returned user name if present
|
|
|
|
lpdwUserNameLength - length of user name buffer
|
|
|
|
lpszPassword - returned password if present
|
|
|
|
lpdwPasswordLength - length of password buffer
|
|
|
|
lpszUrlPath - returned, canonicalized URL path
|
|
|
|
lpdwUrlPathLength - length of url-path buffer
|
|
|
|
lpszExtraInfo - returned search string or intra-page link if present
|
|
|
|
lpdwExtraInfoLength - length of extra info buffer
