Global limit_handles



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

static unspecified limit_handles;


The limit_handles property sets all properties to be inherited only expcitly. It closes all unused file-descriptors on posix after the fork and removes the inherit flags on windows.

[Note] Note

This is executed after the fork on posix.

system("gcc", limit_handles);

Since limit also closes the standard handles unless they are explicitly redirected they can be ignored by limit_handles in the following way.

system("gcc", limit_handles.allowStd())
