Synopsis

Allocate an OCR result buffer.

Syntax

MIL_ID MocrAllocResult(

MIL_ID SystemId,	//in
MIL_INT64 InitFlag,	//in
MIL_ID *ResultOcrIdPtr	//out

)

Description

This function allocates a result buffer for use with other OCR functions. You should check if the operation was successful by verifying that the OCR result buffer identifier returned is not M_NULL.

When the result buffer is no longer required, you should release it using the MocrFree() function.

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

SystemId INQ

Specifies the system on which to allocate the OCR result buffer.

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().

InitFlag

Reserved for future expansion. This parameter must be set to M_DEFAULT.

ResultOcrIdPtr

Specifies the address of the variable to which the OCR result buffer identifier is to be written. Since the MocrAllocResult() function also returns the OCR result buffer identifier, you can set this parameter to M_NULL.

Return value

The returned value is the result buffer identifier if the allocation is successful. If allocation fails, M_NULL is returned.

Compilation information

Header	Include mil.h.
Library	Use mil.lib; milocr.lib.
DLL	Requires mil.dll; milocr.dll.
