5.24.7 Str_Printf
String Functions Example
Syntax
void Str_Printf(char str[], char format[], ...);
Sub Str_Printf(ByRef str As Char, ByRef format As Char, ...)
Description
This function creates a formatted string into str. The format string is similar to the formatting of printf() in C.
The format always begins with "%", then follow optional flags (0,l), and it ends with a type (d,x,s,f). In the
following table all type parameters are explained. Between % and type an optional width and precision
can be used.
%[flags][width][.prec]Typ (the brackets describes the optional part)
The width is the minimal space for the output of the number. If the number is smaller than width, the num-
ber is padded to the left with spaces. If the width begins with "0" the left is padded width "0" instead of
spaces. A period "." describes an optional precision parameter, that defines the number of decimal
places, when floating point numbers (%f) are used, or the base of the number when using unsigned in-
teger (%u). See Str_Printf Example.
If there is no "l" flag when a 32-Bit number is printed, only the lower 16 bits are displayed.
