#25475 [Com]: Direct IO access to raw file descriptor

ID: 25475 Comment by: php at kanarpiet dot com Reported By: mbostrom at syrah dot us Status: Open Bug Type: Feature/Change Request Operating System: Unixes PHP Version: Irrelevant New Comment: It would indeed be very nice to be able to use the extra file descriptors opened by the parents proc_open() call. However, you should also be able to use the normal fgets() and fputs() functions, not just the Direct IO ones. Previous Comments: ------------------------------------------------------------------------ [2003-09-10 15:08:40] mbostrom at syrah dot us Description: ------------ The Direct IO functions are nice. However, it is sometimes necessary to access file descriptors by their number. For instance, a parent process can set up file descriptors 3, 4 and 5 for communication with the a child process (in addition to file descriptors 0, 1 and 2). It would be nice if there were a way in PHP to get access to to file descriptor 3, so that PHP could interoperate with software that uses "extra" file descriptors. (In particular, I am writing a mail filter. The mail server sets up fd 3). Getting access to the "extra" file descriptors is not possible at present, because the only way to get a file descriptor is to call dio_open on a file. What if the file descriptor already exists? There is currently no way to access it. Perhaps a function such as dio_rawfd (int fdnum) could be added? fdnum is an integer - the number of the file descriptor you want. dio_rawfd returns a file descriptor resource for file descriptor number fdnum. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=25475&edit=1
