We need something which + accepts a program name, and a list of arguments, so that + we don't have to assemble together a correctly quoted string. + popen needs an alternative interface resembling execvp. + + * eval.c (eval_init): New intrinsic registered, open-pipe-args. + + * stream.c (struct stdio_handle): New member, pid. + (stdio_stream_print): Print the pid, if it is nonzero. + (pipevp_close): New close function. + (pipe_close): If h->pid is nonzero, it's a new-style pipe, which + must be closed with pipev_close. + (make_stdio_stream, make_pipe_stream): Initialize new stdio_handle + member to zero. + (make_pipevp_stream): New static function. + (open_pipevp): New function. + + * stream.h (open_pipevp): Declared. + + * txr.1: open-pipe-args added to stub section heading. + 2012-05-17 Kaz Kylheku <kaz@kylheku.com> * match.c (v_collect): Implemented semantics for repeat symbol. |
