/**
* The InitializeSecurityContext function initiates the client side, outbound security
* context from a credential handle. The function is used to build a security context
* between the client application and a remote peer. InitializeSecurityContext returns
* a token that the client must pass to the remote peer, which the peer in turn submits
* to the local security implementation through the AcceptSecurityContext call. The
* token generated should be considered opaque by all callers.
*
* Typically, the InitializeSecurityContext function is called in a loop until a
* sufficient security context is established.
*
* @param phCredential
* A handle to the credentials returned by AcquireCredentialsHandle. This handle is
* used to build the security context. The InitializeSecurityContext function requires
* at least OUTBOUND credentials.
* @param phContext
* A pointer to a CtxtHandle structure. On the first call to InitializeSecurityContext,
* this pointer is NULL. On the second call, this parameter is a pointer to the handle
* to the partially formed context returned in the phNewContext parameter by the first
* call.
* @param pszTargetName
* A pointer to a null-terminated string that indicates the target of the context.
* The string contents are security-package specific.
* @param fContextReq
* Bit flags that indicate requests for the context. Not all packages can support all
* requirements. Flags used for this parameter are prefixed with ISC_REQ_, for example,
* ISC_REQ_DELEGATE.
* @param Reserved1
* This parameter is reserved and must be set to zero.
* @param TargetDataRep
* The data representation, such as byte ordering, on the target. This parameter can be
* either SECURITY_NATIVE_DREP or SECURITY_NETWORK_DREP.
* @param pInput
* A pointer to a SecBufferDesc structure that contains pointers to the buffers supplied
* as input to the package. The pointer must be NULL on the first call to the function.
* On subsequent calls to the function, it is a pointer to a buffer allocated with enough
* memory to hold the token returned by the remote peer.
* @param Reserved2
* This parameter is reserved and must be set to zero.
* @param phNewContext
* A pointer to a CtxtHandle structure. On the first call to InitializeSecurityContext,
* this pointer receives the new context handle. On the second call, phNewContext can be
* the same as the handle specified in the phContext parameter.
* @param pOutput
* A pointer to a SecBufferDesc structure that contains pointers to the SecBuffer structure
* that receives the output data. If a buffer was typed as SEC_READWRITE in the input, it
* will be there on output. The system will allocate a buffer for the security token if
* requested (through ISC_REQ_ALLOCATE_MEMORY) and fill in the address in the buffer
* descriptor for the security token.
* @param pfContextAttr
* A pointer to a variable to receive a set of bit flags that indicate the attributes of
* the established context. Flags used for this parameter are prefixed with ISC_RET,
* such as ISC_RET_DELEGATE.
* @param ptsExpiry
* A pointer to a TimeStamp structure that receives the expiration time of the context.
* It is recommended that the security package always return this value in local time.
* This parameter is optional and NULL should be passed for short-lived clients.
* @return
* If the function succeeds, the function returns one of the SEC_I_ success codes.
