Class close_fds_if

Class close_fds_if

boost::process::initializers::close_fds_if

Synopsis

// In header: <boost/process/initializers.hpp>


class close_fds_if {
public:
  // construct/copy/destruct
  explicit close_fds_if(const predicate_type &);
};

Description

Closes all file descriptors a predicate returns true for.

This initializer doesn't close file descriptors immediately. Instead it sets the FD_CLOEXEC flag. File descriptors are closed when execve is called and the call succeeds.

POSIX only.
