Description

This function restores an Edge Finder context that was previously saved to a file, using MedgeSave() or MedgeStream(). This function restores all the Edge Finder context's settings that were in effect when the Edge Finder context 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 if there is complementary information.
Parameters
This function is not supported on the selected boards.
Parameters
FileName

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

This parameter can be set to one of the following:

function map For specifying the file name and path
CollapseValue Description
Collapse M_INTERACTIVE
[This is only applicable to Windows]

Opens the File Open dialog box from which you can interactively specify the drive, directory, and name of the file.

Collapse MIL_TEXT("FileName") 1

Specifies the drive, directory, and name of the file (for example, "C:\mydirectory\myfile").

To specify the file on the remote computer (under Distributed MIL), prefix the specified file name string with "remote:///" (for example, "remote:///C:\mydirectory\myfile").

(summarize)

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

SystemId

Specifies the system on which to restore the Edge Finder context.

This parameter should be set to one of the following values:

function map For specifying the system identifier
CollapseValue Description
Collapse M_DEFAULT_HOST

Specifies the default Host system of the current MIL application.

Collapse MIL system identifier

Specifies a valid system identifier, previously allocated using MsysAlloc().

ControlFlag

Reserved for future expansion and must be set to M_DEFAULT.

ContextIdPtr

Specifies the address of the variable in which to write the Edge Finder context identifier. Since the MedgeRestore() function also returns the Edge Finder 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 Edge Finder context identifier. If allocation fails, M_NULL is returned.
