quotes. For that reason, you can't specify the single quote itself within
a single-quoted string.

## Built-in Functions ##
QSEAWK provides the following built-in functions.
### setioattr (io-name, attr-name, attr-value) ###
It changes the I/O attribute of the name attr-name to the value attr-value
for an I/O stream identified by io-name. It returns 0 on success and -1 on
failure.
- io-name is a source or target name used in getline, print, printf combined
with |, ||, >, <, >>.
- attr-name is one of codepage, ctimeout, atimeout, rtimeout, wtimeout.
- attr-value varies depending on attr-name.
-- codepage: cp949, cp950, utf8
-- ctimeout, atimeout, rtimeout, wtimeout: the number of seconds. applies to socket based stream only. you may use a floating-point number for lower resoluation than a second. a negative value turns off timeout.
#
# Convert a document encoded in cp949 to a current codepage
#
BEGIN
{
setioattr ("README.INS", "codepage", "cp949");
while ((getline x < "README.INS") > 0) print x;
}
### getioattr (io-name, attr-name) ###
It returns the current attribute value of the attribute named attr-name for
the stream identified by io-name. See setioattr for description on io-name and
attr-name. It returns the attribute value on success and -1 on failure.
