Classes
class	process::Subprocess
	Represents a fork() exec()ed subprocess. More...
class	process::Subprocess::IO
	Describes how the I/O is redirected for stdin/stdout/stderr. More...
struct	process::Subprocess::IO::InputFileDescriptors
	For input file descriptors a child reads from the read file descriptor and a parent may write to the write file descriptor if one is present. More...
struct	process::Subprocess::IO::OutputFileDescriptors
	For output file descriptors a child writes to the write file descriptor and a parent may read from the read file descriptor if one is present. More...
struct	process::Subprocess::ParentHook
	A hook can be passed to a subprocess call. More...
class	process::Subprocess::ChildHook
	A ChildHook can be passed to a subprocess call. More...

Functions
Try< Subprocess >	process::subprocess (const std::string &path, std::vector< std::string > argv, const Subprocess::IO &in=Subprocess::FD(STDIN_FILENO), const Subprocess::IO &out=Subprocess::FD(STDOUT_FILENO), const Subprocess::IO &err=Subprocess::FD(STDERR_FILENO), const flags::FlagsBase *flags=nullptr, const Option< std::map< std::string, std::string >> &environment=None(), const Option< lambda::function< pid_t(const lambda::function< int()> &)>> &clone=None(), const std::vector< Subprocess::ParentHook > &parent_hooks={}, const std::vector< Subprocess::ChildHook > &child_hooks={}, const std::vector< int_fd > &whitelist_fds={})
	Forks a subprocess and execs the specified 'path' with the specified 'argv', redirecting stdin, stdout, and stderr as specified by 'in', 'out', and 'err' respectively. More...
