Bulletin number: 115 Products affected: D700D Description: C server file access commands Component: THE SERVERS Date: Tue May 15 17:00:00 GMT 1990 ----- The C server can give a spurious error -312 after an attempt to write to a file opened for block update. The underlying cause is the coding of the call of the C library routine fopen, whose second parameter should be "r+b" rather than "rb+" . There is only one occurrence of this string in the file filer.tsr in the C server source.
