The \c return builtin is used to halt a currently running function. It
|
|
|
|
|
is usually added inside of a conditional block such as an <a
|
|
|
|
|
href="#if">if</a> statement or a <a href="#switch">switch</a>
|
|
|
|
|
statement to conditionally stop the executing function and return to
|
|
|
|
|
the caller, but it can also be used to specify the exit status of a
|
|
|
|
|
function.
|
|
|
|
|
|
|
|
|
|
- \c STATUS is the return status of the function. If unspecified, the status is unchanged.
