+Routine Description:

+
+Arguments:
+
+ InputFile Memory file image.
+ Section The section to search for, a string within [].
+ Instance Specify the Instance-th token to search for, starting from zero
+ Token The token name to return. Caller should allocate the buffer.
+ Must be _MAX_PATH in size.
+ Value The token value to return. Caller should allocate the buffer.
+ Must be _MAX_PATH in size.

+Returns:

+ EFI_ABORTED Format error detected in INF file.
+ EFI_INVALID_PARAMETER Input argument was null.
+ EFI_LOAD_ERROR Error reading from the file.
