Synopsis

Restore a blob context from disk.

Syntax

MIL_ID MblobRestore(

MIL_CONST_TEXT_PTR FileName,	//in
MIL_ID SysId,	//in
MIL_INT64 ControlFlag,	//in
MIL_ID *ContextBlobIdPtr	//out

)

Description

This function restores a blob context that was previously saved to a file, using MblobSave() or MblobStream(). This function restores all of the blob context's settings that were in effect when it was saved.

Note that this function reference has not been updated for a MIL system added during a MIL update. Refer to the MIL system's release note to see which MIL system’s documentation you should use in its place and any possible differences.

Parameters

This function is not supported on the selected boards.

This function reference has not been updated for the selected MIL system. To show the content of this page, choose a second MIL system; refer to the MIL system's release note to see which MIL system’s documentation to choose and any possible differences.

Parameters

FileName

Specifies the name and path of the file from which to restore the blob context. The function handles (internally) the opening and closing of the file.

This parameter should be set to the following value:

For specifying the file name and path
Value	Description
MIL_TEXT("FileName") ¹	Specifies the drive, directory, and name of the file (for example, "C:\mydirectory\myfile"). Typically, blob contexts have a MBLOB file extension. To specify a file on a remote computer (under Distributed MIL), prefix the specified file name string with "remote:///" (for example, "remote:///C:\mydirectory\myfile"). (summarize) Specifies the drive, directory, and name of the file (for example, "C:\mydirectory\myfile"). (more details...)

¹ If you are passing the value in a variable, don't enclose it in MIL_TEXT().

SysId

Specifies the identifier of the system on which to restore the blob 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 MIL application.
MIL system identifier	Specifies a valid system identifier, previously allocated using MsysAlloc().

ControlFlag

Reserved for future expansion and must be set to M_DEFAULT.

ContextBlobIdPtr

Specifies the address of the variable in which to write the blob context identifier. Since this function also returns the blob context identifier, you can set this parameter to M_NULL. If allocation fails, M_NULL is written as the identifier.

Return value

The returned value is the blob context identifier. If allocation fails, M_NULL is returned.

Remark

The prototypes of functions in the Mblob module changed as of MIL 10 PP2. For C applications, by default the original prototypes are used to ensure backward-compatibility. To use the updated prototypes, add #define M_USE_OLD_MBLOB_API_IN_C 0 before including mil.h. For information about the original API for the Mblob module refer to the MIL 10 PP1 documentation, available online to registered users at https://www.matrox.com/imaging/en/products/software/mil/documentation/.
