MFS_SHARING_VIOLATION when opening in "a " mode after open in "r" mode

[Fabi]

When I open a file with "r" option, then closing it and opening it again with "a+" mode,

MQX runs in MFS_SHARING_VIOLATION in mfs_open.c:

	// If we are opening to write, the file can't already be opened.
	if ((access == MFS_ACCESS_WRITE_ONLY) || (access == MFS_ACCESS_READ_WRITE)) {
	error_code = MFS_SHARING_VIOLATION;
	}

What's wrong (with my calls)? Any ideas?

Hi F.Bilz

Did you solve this problem?

Thanks.

It was an application issue. In some circumstances, where was no "closing" between the two "openings".
