69cb752813 Add CRC8 support. From Ken Pettit 2014-12-09 13:27:22 -06:00

297a255fd8 avsprintf(): Fix a bug in usage of va_list on x86. On x86, va_list is a 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 2014-12-08 10:40:06 -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

639641dc04 The definition of strncpy() is that empty space should be zero-filled, the 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. 2014-11-12 07:36:15 -06:00

c23b7ec93d From Lorenz Meier: The implementation of access() as vararg macro has the 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. 2014-11-11 11:52:24 -06:00

bbc658930a Passing va_list in syscall does not work. Temporarily moved syslog and lowsyslog into kernel code and access via a system call. Need to revisit. Will probably need to move all of syslog back from fs/syslog to libc/syslog 2014-10-08 20:12:52 -06:00
