NAME
       vscnprintf - Format a string and place it in a buffer

SYNOPSIS
       int vscnprintf(char * buf, size_t size, const char * fmt, va_list args);

ARGUMENTS
       buf
           The buffer to place the result into

       size
           The size of the buffer, including the trailing null space

       fmt
           The format string to use

       args
           Arguments for the format string

DESCRIPTION
       The return value is the number of characters which have been written into the buf not
       including the trailing '\0'. If size is == 0 the function returns 0.

       If you're not already dealing with a va_list consider using scnprintf.

       See the vsnprintf documentation for format string extensions over C99.
