e73e82a923 Move prototypes of mkfifo2() from sys/stat.h and pipe2() from unistd.h. They are non-standard and should not be in such a public place. They are not in include/nuttx/fs/fs.h (which isn't a great place either). 2016-07-20 11:57:18 -06:00

6cefbc0c3f This change provides an option to add /dev/urandom to all architectures. The pseudo-random algorithm I choose strikes an arguably-good balance between being "random" and small/fast enough for 8/16 bit MCUs. It’s the well-documented xorshift128 algorithm. It has an internal state of 128 bits that can be [re-]seeded with a write. 2016-07-17 06:42:26 -06:00

82c890db23 syslog_dev_flush() needs to check if the inode is a mountpoint before calling the flush() method. Noted by David Sidrane. 2016-06-22 05:58:33 -06:00

001715d57b FS: Add logic to detach a file structure from a file descriptor. This is for use only within the OS. It permits an open file or driver to be used across multiple threads. 2016-05-26 09:41:50 -06:00

eb1aca3e46 Add an unlink method to block driver interface. Same motivataion as for the same modification to the character driver interface 2015-01-31 13:19:23 -06:00

62e588a0a4 VFS: Add an unlink method to the character driver interface. This is important because if the character driver inode is unlinked and there are no open references to the driver, then the driver resources will be stranded. On the unlink call, the driver has the opportunity (1) check if there an any open references, and (2) if not free the driver resources 2015-01-31 11:31:34 -06:00

e31d5125ae Add support for a variadic ioctl() function. The ioctl() interface is a non-standard, Unix interface. NuttX has always used the older, three-parameter version. Most contemporary systems now, however, use a variadic form of the ioctl() function. Added an option to insert a shim layer to adapt the three-parameter ioctl() to use the variadic interface form. Internally, the ioctl handling is the same three-parameter logic. The only real complexity to the shim is in how the system calls must be handled. 2014-11-29 10:53:22 -06:00
