Description:
|
The save identifier written with C printf format "%s ". Read an entity identifier. In text mode, this is just a sequence of non-blank characters. In binary mode, it is a sequence of counted strings, of which all but the last have negative counts. These strings are assembled into the buffer, separated by '-'. The result is placed in a caller-supplied buffer - overflow causes an error, unless the length is given zero or negative, in which case no overflow is detected.
ActiveFile is a
FileInterface object and does most of the actual work.
