NAME
Proc::Hevy::Writer - A writer pipe implementation for Proc::Hevy
DESCRIPTION
Proc::Hevy::Writer implements a writer pipe that writes data to a child process from a provided buffer. This is used when writing to a child process's STDIN.
INTERFACE
new( $name, $buffer )
Creates a new Proc::Hevy::Writer object. $name is a symbolic name for the writer. $buffer is the source mechanism to used for data written to the child process. It can either be a simple scalar, an ARRAY reference, a CODE reference or a GLOB reference.
child( $handle )
Performs actions suitable when running as part of the child process. This includes re-opening the provided $handle to a filehandle that is created based on the type of source buffer configured in new(). If no buffer was configured, '/dev/null' is opened for reading.
parent( $select )
Performs actions suitable when running as part of the parent process. This includes adding filehandles to the provided $select object that should be monitored for writability.
write
Performs the actual write to the child process consuming data from the source buffer configured in new(). When the source buffer is empty, applicable filehandles are closed and removed from the select object used in the call to parent(). Any system errors are considered fatal.
BUGS
None are known at this time, but if you find one, please feel free to submit a report to the author.
