.th GETCHAR
|
|
.sh NAME
|
|
getchar \*- read character
|
|
.sh SYNOPSIS
|
|
.ft B
|
|
int getchar( )
|
|
.br
|
|
.ft R
|
|
.sh DESCRIPTION
|
|
Getchar reads records from the standard input (VERSAdos file #5)
|
|
into a buffer and returns these characters one per call to the
|
|
user. Getchar assumes that it is reading ASCII records. It
|
|
places a '\\n' character on the end of each record, and translates
|
|
the VERSAdos tab character (any negative character) into a '\\t'.
|
|
Getchar returns a negative number for EOF or read error.
|
|
Since all VERSAdos I/O is record I/O, getchar must be buffered,
|
|
and thus is not any less efficient than getc.
