There is no sprint function in any C library of which I am aware.  You are
probably thinking of sprintf, but even that function is of no help in
extracting
numbers from a string.  To do that, in C, one would use scanf, or one of its
companion xscanf functions.

That said, to do the same thing in Ada, one would make use of the 'Value
attribute of the corresponding numeric type to obtain the numeric
value from its string representation.

For example, to obtain the numeric value from a string of digits, one
would use the Integer'Value function, passing the string as the argument.

To tokenize a string (say, from a file), one would use the Find_Token
procedure of the Ada.Strings.Fixed package.
