Printf functions
These function permits to print any data on a printing device. These functions work as the printf function, except that they include the fixed point Q formatted format notion. The following attributes are currently implemented: s : The const char * argument is expected to be a pointer to an array of character type (pointer to a string). Characters from the array are written up to (but not including) a terminating null byte ('\0'); if a precision is specified, no more than the number specified are written. If a precision is given, no null byte need be present; if the precision is not specified, or is greater than the size of the array, the array must contain a terminating null byte. d ,i : The int argument is converted to signed decimal notation. The precision, if any, gives the minimum number of digits that must appear; if the converted value requires fewer digits, it is padded on the left with zeros. The default precision is 1. When 0 is printed with an explicit precision 0, the output is empty. o ,u ,x ,X : The unsigned int argument is converted to unsigned octal (o ), unsigned decimal (u ), or unsigned hexadecimal (x and X ) notation. The letters abcdef are used for x conversions; the letters ABCDEF are used for X conversions. The precision, if any, gives the minimum number of digits that must appear; if the converted value requires fewer digits, it is padded on the left with zeros. The default precision is 1. When 0 is printed with an explicit precision 0, the output is empty. c : The int argument is converted to an unsigned char, and the resulting character is written. f : The fixed point argument is converted to decimal notation in the style [-]ddd.ddd, [THE FOLLOWING IS NOT IMPLEMENTED YET!] where the number of digits after the decimal-point character is equal to the precision specification. If the precision is missing, it is taken as 6; if the precision is explicitly zero, no decimal-point character appears. If a decimal point appears, at least one digit appears before it.
