* sscanf should also support %FGregory Nutt2014-12-121-1/+1

* sscanf: Accept %X as well as %x as a format specifier. From Sébastien LorquetGregory Nutt2014-12-121-0/+1

* Cosmetic change to force compliance with coding standardGregory Nutt2014-12-121-1/+5

| | | | memory if n == 0. From Hiro
* Add CRC8 support. From Ken PettitGregory Nutt2014-12-092-1/+142
|
* avsprintf(): Fix a bug in usage of va_list on x86. On x86, va_list is a ↵Gregory Nutt2014-12-081-3/+30
| | | | pointer to a single copy on the stack. avsprintf() calls lib_vsprintf() twice and so traverses the va_list twice using va_start. va_start modifies that single copy on the stack so that the second call to lib_vsprintf() fails. This appears to be an issue with x86 only so far
* Traveler: Change the way that the world path is managed.Gregory Nutt2014-12-081-1/+1

* Update some Documentation and comments associated with the last ioctl changeGregory Nutt2014-11-291-2/+2

* Add some commentsGregory Nutt2014-11-292-2/+10
|
* Add support for a variadic ioctl() function. The ioctl() interface is a ↵Gregory Nutt2014-11-293-0/+137
| | | | 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.
* Another fix misthink in big cppcheck changedGregory Nutt2014-11-251-1/+1

* More fixes to problems noted by cppcheck. Some are kind of risky; some are ↵Gregory Nutt2014-11-252-1/+2

* execl() no longer depends on CONFIG_MAX_TASK_ARGSGregory Nutt2014-11-121-8/+45
|
* The definition of strncpy() is that empty space should be zero-filled, the ↵Gregory Nutt2014-11-121-1/+2
| | | | patch adds the zero filling (I didn’t know this, see e.g. the POSIX spec here: http://pubs.opengroup.org/onlinepubs/7908799/xsh/strncpy.html). From Lorenz Meier.
* From Lorenz Meier: The implementation of access() as vararg macro has the ↵Gregory Nutt2014-11-112-1/+94
| | | | issue that any function call with the same name (even in a C++ class) will match with it and result in a compile error. I have replaced it with a small function, and tried to have decent documentation as well. This resolves the compile issue, and shouldn’t have negative side effects for users of the function.
* EFM32: Fix issues associated with SPI bi order. From PierreGregory Nutt2014-11-091-1/+1

* Backing out some logic: Remove syslog functions from syscallsGregory Nutt2014-10-091-0/+5

* Passing va_list in syscall does not work. Temporarily moved syslog and ↵Gregory Nutt2014-10-085-252/+0
