<p>A function to format and print a string (fmt) to an out string (str), limited to a given amount of characters (size). </p>
|
|
<p>This function generally uses the well-known C language standard print format, but only a subset is supported. The following options are supported.</p>
|
|
<p>Format tags begin with a '\%' character and are followed by an optional sequence of flags, an optional field width, an optional precision, an optional type size specification, and a mandatory conversion specifier.</p>
|
|
<p>Supported flags:</p>
|
|
<p>'+' (plus) if the number is positive use a '+' character in front of the number.</p>
|
|
<p>' ' (space) if the number is positive, use a white space in front of the number.</p>
|
|
<p>'-' (minus) left justify within field width (otherwise: right justify). A negative field width also triggers this option.</p>
|
|
<p>'0' (zero) left fill with zeros to field width (otherwise: white space).</p>
|
|
<p>'\#' (hash) use alternative syntax; semantics depends on conversion specifier</p>
|
|
<p>Field width:</p>
|
|
<p>A decimal number using '0'..'9' characters: minimum number of characters to use in output string.</p>
|
|
<p>'*' (asterisk): the field width is provided by an 'int' argument.</p>
|
|
<p>Precision:</p>
|
|
<p>This always starts with a '.' (period) followed by:</p>
|
|
<p>A decimal number using '0'..'9' characters: precision to use for formatting. The exact sematics depends on the conversion specifier.</p>
|
|
<p>'*' (asterisk): the precision is provided by an 'int' argument.</p>
|
|
<p>Type size:</p>
|
|
<p>'hh': an integer the same size as 'char'</p>
|
|
<p>'h': an integer the same size as 'short'</p>
|
|
<p>'l': an integer the same size as 'long'</p>
|
|
<p>'ll': an integer the same size as 'long long'</p>
|
|
<p>'z': an integer the same size as 'size_t' (or 'P4_size_t')</p>
|
|
<p>'t': an integer the same size as 'ptrdiff_t'</p>
|
|
<p>Format specifiers:</p>
|
|
<p>'c': a single character: '\#' and precision are ignored.</p>
|
|
<p>'s': a string: '\#' is ignored. precision is the maximum number of characters at the beginning of the string to be formatted.</p>
|
|
<p>'d', 'i': decimal signed integer. '\#' is ignored. the precision is the minimum number of zeros printed; default precision is 0.</p>
|
|
<p>'u': decimal unsigned integer. '\#' and precision works like with 'd'.</p>
|
|
<p>'x': hexadecimal integer. '\#' will cause printing '0x' prefix if the number is not 0. Precision works like with 'd'.</p>
|
|
<p>'X': same as 'x', but uses upper case characters.</p>
|
|
<p>'o': octal integer. '\#' will cause printing '0' prefix if number is not 0. Precision works like with 'd'.</p>
|
|
<p>'p': prints void* pointer. Works like 'x', but with a pointer argument interpreted as integer.</p>
|
|
<p>'P': same as 'p', but uses upper case characters.</p>
|
