Arguments: simple-stream
This generic function tries to determine the character position of
its simple-stream
argument, similar to stream-line-column which tries to determine
the character number from the beginning of a line. The value returned
is a non-negative integer or nil.
nil means that the value cannot be
determined. This can happen, for example, if bytes rather than
characters have been read from simple-stream or the file-position has
been set. Unlike stream-line-column, which can re-synchronize
itself after reading a newline, file-character-position cannot; it can only
re-synchronize itself when the file-position starts at zero and only
characters are read.
