edftell — Obtains the current value of the sample position indicator
[seek]=edftell(handle,edfsignal);
: a integer containing the file handle of the opened bdf/gdf-file
: Minimum value is 1.
: current offset
The edftell function obtains the current value of the sample position indicator for the edfsignal pointed to by edfsignal. Returns the current offset. Otherwise, -1 is returned Note that every signal has it's own independent sample position indicator and edftell() affects only one of them.
