If an error does occur, the function should return @code{EOF} and set -@code{*errcode} to a non-zero value. In that case, if @code{*errcode} -does not equal @minus{}1, @command{gawk} automatically updates +@code{*errcode} to a value greater than zero. In that case, if @code{*errcode} +does not equal zero, @command{gawk} automatically updates the @code{ERRNO} variable based on the value of @code{*errcode}. (In general, setting @samp{*errcode = errno} should do the right thing.) |
