int cscanf( const char *format, ... );
.ixfunc2 '&KbIo' &func
.funcend
.desc begin
The &func function scans input from the console
under control of the argument
.arg format.
Following the format string is a list of addresses to receive values.
The &func function uses the function
.kw getche
to read characters from the console.
The
.arg format
string is described under the description of the
.kw scanf
function.
.desc end
.return begin
The &func function returns
.kw EOF
when the scanning is terminated by reaching the end of the input stream.
Otherwise, the number of input arguments for which
values were successfully scanned and stored is returned.
When a file input error occurs, the
.kw errno
global variable may be set.
