Restore a blob analysis context from disk.
Syntax
AIL_ID MblobRestore(
AIL_CONST_TEXT_PTR FileName, //in
AIL_ID SysId, //in
AIL_INT64 ControlFlag, //in
AIL_ID * ContextBlobIdPtr //out
)
Description
This function restores a blob analysis context that was previously saved to a file, using MblobSave or MblobStream. This function restores all of the blob analysis context's settings that were in effect when it was saved.
When the restored blob analysis context is no longer required, release it usingMblobFreeunless M_UNIQUE_ID was specified during allocation; if M_UNIQUE_ID was specified, the smart identifier manages the blob analysis context's lifetime and you must not manually free it.
Parameters
FileName (in, AIL_CONST_TEXT_PTR)
Specifies the name and path of the file from which to restore the blob analysis context. The function handles (internally) the opening and closing of the file.
For specifying the file name and path
| Value | Description |
|---|---|
"FileName" | Specifies the drive, directory, and name of the file (for example, "C:\mydirectory\myfile"). Typically, blob analysis contexts have a MBLOB file extension. |
To specify a file on a remote computer (under Distributed Aurora Imaging Library), prefix the specified file name string with "remote:///" (for example, "remote:///C:\mydirectory\myfile"). |
SysId (in, AIL_ID)
Specifies the identifier of the system on which to restore the blob analysis context. This parameter should be set to one of the following values:
For specifying the system identifier
| Value | Description |
|---|---|
M_DEFAULT_HOST | Specifies the default Host system of the current Aurora Imaging Library application. |
System identifier | Specifies a valid system identifier, previously allocated using MsysAlloc. |
ControlFlag (in, AIL_INT64)
Reserved for future expansion and must be set to M_DEFAULT.
ContextBlobIdPtr *(out, AIL_ID)
Specifies the address of the variable in which to write the blob analysis context identifier or specifies the data type that the function should use to return the Blob Analysis context identifier.
For retrieving the identifier or specifying how to return it
| Value | Description |
|---|---|
M_NULL | Specifies that you will use this function's return value to obtain the identifier of the allocated blob analysis context; in this case, a standard Aurora Imaging Library identifier of type AIL_ID is returned. |
M_UNIQUE_ID | Specifies that you will use this function's return value to obtain the identifier of the allocated blob analysis context; in this case, an Aurora Imaging Library smart identifier of type _AIL_UNIQUE_BLOB_ID_is returned instead of a standard Aurora Imaging Library identifier.This setting is only available when using C++11 (or later).An Aurora Imaging Library smart identifier manages the lifespan of the Aurora Imaging Library object it owns (similar to a std::unique_ptr). Note, you can use an Aurora Imaging Library smart identifier as though it were a standard Aurora Imaging Library identifier, except that you cannot use it to manually free the blob analysis context (it is freed automatically). For more information, see Aurora Imaging Library smart identifiers. |
Address in which to write the identifier | Specifies the address of an AIL_ID in which to write the identifier of the restored blob analysis context. |
If restoration fails, M_NULL is written as the identifier. |
Return Value
Type: AIL_ID
The returned value is the blob analysis context identifier either as a standard identifier (AIL_ID) or a smart identifier (AIL_UNIQUE_BLOB_ID). If allocation fails, M_NULL is returned (or nullptr ifM_UNIQUE_ID was specified).
