Hi >>> Luc Lefebvre <luc.lefebvre_at_mcgill.ca> 30.05.03 18.23 Uhr >>> Have you looked at the mmap program in comedilib/demo? 1) Can the memmapping also be used in connection with dio especially the NI PCI 32HS board and driver? 2) Is it possible to devide the streaming buffer into three independen Memmaps which contain consecutive Data?? Means one mmap contains data which has allready bben read and therefore is invalid. 1 is in state of beeinf filled by comedi and one beeing read by user process? 3) is comedi capable of informing userapplication that an entire mmap is valid and can be read? In other word is comedy capable to send user application to sleeb until entire mmap which is awaited is filled with valid data again ? cu Christoph _______________________________________________ comedi mailing list comedi_at_comedi.org https://cvs.comedi.org/cgi-bin/mailman/listinfo/comedi
