redi::basic_ipstream(3) Library Functions Manual redi::basic_ipstream(3) NAME
redi::basic_ipstream - Class template for Input PStreams. SYNOPSIS
#include <pstream.h> Inherits redi::pstream_common< CharT, Traits >, and redi::pstreams. Public Types typedef pbase_type::pmode pmode Type used to specify how to connect to the process. typedef pbase_type::argv_type argv_type Type used to hold the arguments for a command. typedef int fd_type Type used for file descriptors. typedef int fd_type Type used for file descriptors. Public Member Functions basic_ipstream () Default constructor, creates an uninitialised stream. basic_ipstream (const std::string &command, pmode mode=pstdout) Constructor that initialises the stream by starting a process. basic_ipstream (const std::string &file, const argv_type &argv, pmode mode=pstdout) Constructor that initialises the stream by starting a process. ~basic_ipstream () Destructor. void open (const std::string &command, pmode mode=pstdout) Start a process. void open (const std::string &file, const argv_type &argv, pmode mode=pstdout) Start a process. basic_ipstream & out () Set streambuf to read from process' stdout. basic_ipstream & err () Set streambuf to read from process' stderr. void close () Close the pipe. bool is_open () const Report whether the stream's buffer has been initialised. const std::string & command () const Return the command used to initialise the stream. streambuf_type * rdbuf () const Return a pointer to the stream buffer. Static Public Attributes static const pmode pstdin = std::ios_base::out Write to stdin. static const pmode pstdout = std::ios_base::in Read from stdout. static const pmode pstderr = std::ios_base::app Read from stderr. static const pmode pstdin = std::ios_base::out Write to stdin. static const pmode pstdout = std::ios_base::in Read from stdout. static const pmode pstderr = std::ios_base::app Read from stderr. Protected Types typedef basic_pstreambuf< CharT, Traits > streambuf_type enum { bufsz = 32 } enum { pbsz = 2 } enum { bufsz = 32 } enum { pbsz = 2 } Protected Member Functions void do_open (const std::string &command, pmode mode) Start a process. void do_open (const std::string &file, const argv_type &argv, pmode mode) Start a process. Protected Attributes std::string command_ The command used to start the process. streambuf_type buf_ The stream buffer. Detailed Description template<typename CharT, typename Traits = std::char_traits<CharT>>class redi::basic_ipstream< CharT, Traits > Class template for Input PStreams. Reading from an ipstream reads the command's standard output and/or standard error (depending on how the ipstream is opened) and the command's standard input is the same as that of the process that created the object, unless altered by the command itself. Constructor &; Destructor Documentation template<typename CharT , typename Traits = std::char_traits<CharT>> redi::basic_ipstream< CharT, Traits >::basic_ipstream (const std::string &command, pmodemode = pstdout) [inline] Constructor that initialises the stream by starting a process. Initialises the stream buffer by calling do_open() with the supplied arguments. Parameters: command a string containing a shell command. mode the I/O mode to use when opening the pipe. See also: do_open(const std::string&, pmode) template<typename CharT , typename Traits = std::char_traits<CharT>> redi::basic_ipstream< CharT, Traits >::basic_ipstream (const std::string &file, const argv_type &argv, pmodemode = pstdout) [inline] Constructor that initialises the stream by starting a process. Initialises the stream buffer by calling do_open() with the supplied arguments. Parameters: file a string containing the pathname of a program to execute. argv a vector of argument strings passed to the new program. mode the I/O mode to use when opening the pipe. See also: do_open(const std::string&, const argv_type&, pmode) template<typename CharT , typename Traits = std::char_traits<CharT>> redi::basic_ipstream< CharT, Traits >::~basic_ipstream () [inline] Destructor. Closes the stream and waits for the child to exit. Member Function Documentation template<typename C , typename T > void redi::pstream_common< C, T >::close () [inline, inherited] Close the pipe. Calls rdbuf->close() and sets failbit on error. template<typename C , typename T > const std::string & redi::pstream_common< C, T >::command () const [inline, inherited] Return the command used to initialise the stream. Returns: a string containing the command used to initialise the stream. template<typename C , typename T > void redi::pstream_common< C, T >::do_open (const std::string &command, pmodemode) [inline, protected, inherited] Start a process. Calls rdbuf()->open( command , mode ) and sets failbit on error. Parameters: command a string containing a shell command. mode the I/O mode to use when opening the pipe.

Calls rdbuf()->open( file, argv, mode ) and sets failbit on error. Parameters: file a string containing the pathname of a program to execute. argv a vector of argument strings passed to the new program. mode the I/O mode to use when opening the pipe.
