printf
See sprintf. This function write the result in the log file.
Prototype :
fun [S u0 I] S
- S : the formatted string. Currently, theses conversion specifiers are
availables such as %d, %f, %x, %s, eventually with a precision (see
sprintf for details).
- u0 : a polymorphic tuple. Its size should be
equal at the number of conversion specifiers. Otherwise, if the size is lesser,
the last converters will be ignored. If the size is greater, the last items
will be ignored. If an item is nil, the converter will be write again.
Note : if it is not a tuple, the behavior is undefined.
- I : the log mask (0, 1, 2, 4, 8 or 16)
Return : S a new string or nil if error
