CredReadW function (wincred.h)
The CredRead function reads a credential from the user's credential set. The credential set used is the one associated with the logon session of the current token. The token must not have the user's SID disabled.
BOOL CredReadW( LPCWSTR TargetName, DWORD Type, DWORD Flags, PCREDENTIALW *Credential );
Pointer to a null-terminated string that contains the name of the credential to read.
Type of the credential to read. Type must be one of the CRED_TYPE_* defined types.
Currently reserved and must be zero.
Pointer to a single allocated block buffer to return the credential. Any pointers contained within the buffer are pointers to locations within this single allocated block. The single returned buffer must be freed by calling CredFree.
The function returns TRUE on success and FALSE on failure. The GetLastError function can be called to get a more specific status code. The following status codes can be returned:
No credential exists with the specified TargetName.
The logon session does not exist or there is no credential set associated with this logon session. Network logon sessions do not have an associated credential set.
A flag that is not valid was specified for the Flags parameter.
If the value of the Type member of the CREDENTIAL structure specified by the Credential parameter is CRED_TYPE_DOMAIN_EXTENDED, a namespace must be specified in the target name. This function can return only one credential of the specified type.
The wincred.h header defines CredRead as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors.
