void mdb_set_pipe(const mdb_pipe_t *p);
Set the pipeline output buffer to the contents described by the pipe structure p. The pipe values are placed in the array p->pipe_data, and the length of the array is stored in p->pipe_len. The debugger makes its own copy of this information, so the caller must remember to free p->pipe_data if necessary. If the pipeline output buffer was previously non-empty, its contents are replaced by the new array. If the dcmd was not executed on the left side of a pipeline (that is, the DCMD_PIPE_OUT flag was not set in its flags parameter), this function has no effect.
