+ * Copyright ArcCore AB\r
+ *\r
+ * A simple implementation of all formatted xxprintf functionallity.\r
+ *\r
+ * DESIGN CRITERIA:\r
+ * - Reentrant\r
+ * - Use little stack\r
+ *\r
+ * What you normally would do is to print to a buffer of some kind and then\r
+ * call write(). However little stack indicates that we can't place buffers\r
+ * on the stack and reentrant tells us that we can't have a static buffer.\r
+ * That leaves us with printing characters as it is ready. From a speed\r
+ * point of view that is less than optimal, but that the way it's got to be.\r
+ * (Could make a 16 long char buffer??)\r
+ *\r
+ * This is just intended to be used as a replacement for newlibs implementation.\r
+ * Newlib porting interface have the following API:\r
+ * int write( int fd, char *buf, int nbytes)\r
+ *\r
+ *\r
+ * Note that puts(), putc() are still the newlib variants....\r
+ *\r
+ * printf() -> vfprintf(stdout,) -> vsnprintf(buf,)\r
+ * write()\r
+ * vprintf() -> vfprintf(stdout,) -> vsnprintf(buf,)\r
+ * write()\r
+ * sprintf(buf,) -> vsnprintf(buf,)\r
+ * snprintf(buf,) -> vsnprintf(buf,)\r
+ *\r
+ * IMPLEMENTATION NOTE:\r
+ * - If printing more than the limit, e.g. using vsnprintf() then\r
+ * the emit function will only stop printing, but not interrupted\r
+ * (The code will get more complicated that way)\r
+ * - ANSI-C and POSIX, streams and POSIX filenumbers.\r
+ * POSIX file-numbers exist in unistd.h and are only to be used by the porting\r
+ * newlib interface i.e. newlib_port.c.\r
+ *\r
+ *\r
+ * NEWLIB: File handles vs files\r
+ * This printf() family of functions does not use newlib at all.\r
+ * At this point the following can have happend:\r
+ * 1. A call to any of the file functions in newlib have been called.\r
+ * This then calls a number of functions (sbrk, __sinit(_impure_ptr), etc ).\r
+ * __sinit(_impure_ptr) initializes the standard files, stdin, stdout, stderr.\r
+ * file->_file is the actual posix file number (stdin=0, stdout=1, stderr=2)\r
+ * 2. No calls is done to newlib file functions. The impure_data is then empty and\r
+ * all fields are 0.\r
+ *\r
+ * Code for checking if the newlib have initialized (or we have explicitly called __sinit(_impure_ptr)\r
+ * if( _impure_ptr->__sdidinit == 1 ) {\r
+ * // We use the real filenumber\r
+ * arc_putchar((int)(file->_file), c);\r
+ * )\r
