IOSTREAM* Sopen_pipe(const char *command, const char *type)

Start a process from command and connect the input or output to the returned stream. This wraps the POSIX popen() API. The type string starts with r or w and may be followed by b to create a binary stream. The default is to create a text stream using the platform conventions and locale.
