Member Function Documentation

◆ call()

virtual void BLOCXX_NAMESPACE::WinExec::WinSystemPreExec::call ( pipe_pointer_t const pparr[] )

inlinevirtual

This function is called between fork and exec in the spawn() function.

It must not allocate memory unless you can guarantee that there is only one thread running – on some platforms allocating memory between fork and exec when there were other threads running can result in a deadlock.

Any exception thrown of type PreExec::Error or derived from std::exception is reported in full back to the parent; any exception derived from PreExec::DontCatch is allowed to propagate out of Exec::spawn; and any other type of exception is reported as an unknown exception.

Parameters

pparr an array pointer that can be passed to the static functions close_pipes_on_exec() and setup_std_descriptors(). It includes pipes for each of the standard descriptors, plus any additional pipes used by Exec::spawn for communicating between child and parent before the execve occurs.

Implements BLOCXX_NAMESPACE::Exec::PreExec.

Definition at line 77 of file WinExec.hpp.

◆ keepStd()

virtual bool BLOCXX_NAMESPACE::WinExec::WinSystemPreExec::keepStd ( int d ) const

inlinevirtual

Returns: True if Process object returned by spawn() should contain one end of a pipe connected to standard descriptor d for the child process. False if standard descriptor d of child should be connected to /dev/null.

Precondition: 0 <= d < 3.

Implements BLOCXX_NAMESPACE::Exec::PreExec.
