SecAllocateAndSetIPAddress function (ntifs.h)
The SecAllocateAndSetIPAddress function allocates resources and sets a call target based on an IP address and optional target name.
Syntax
SECURITY_STATUS SEC_ENTRY SecAllocateAndSetIPAddress(
PUCHAR lpIpAddress,
ULONG cchIpAddress,
int *FreeCallContext
);
Parameters
lpIpAddress
[in, optional] A pointer to a buffer containing the IP address of the target. This parameter can be NULL if only the target name is provided.
cchIpAddress
[in] The size, in bytes, of the IP address buffer.
FreeCallContext
[out] Pointer to an integer that indicates whether the call context should be freed. This value is equivalent to a Boolean value, where a non-zero value (TRUE) indicates that the caller is responsible for freeing the context by calling SecFreeCallContext.
Return value
SecAllocateAndSetIPAddress returns SEC_E_OK if the operation is successful. Otherwise, it returns an error code such as one of the following:
| Return code | Description |
|---|---|
| SEC_E_INVALID_PARAMETER | One or more parameters are invalid. |
| SEC_E_INSUFFICIENT_MEMORY | There is not enough memory to complete the operation. |
Remarks
SecAllocateAndSetIPAddress is primarily used to determine if a target is a private or enterprise resource, facilitating Single Sign-On (SSO) operations.
It allows both an IP address and a target name to be specified, providing flexibility in identifying the target resource. One of lpIpAddress or TargetName must be provided; otherwise, the function will return SEC_E_INVALID_PARAMETER.
