const char *input_str,
This routine reads an int from a string with more sophisticated error
reporting that available using scanf. If the contents of "str" is exactly one
number which will fit into an int, it sets *int_ptr to that number and
returns NO_ERROR. Otherwise and error message is set, and ERROR is returned.
The contents of *int_ptr are only changed on success.
If "str" is a valid int, then NO_ERROR is returned. Otherwise the problem
with "str" is reported in the set error message, and ERRROR is returned.
The problem with "str" can be printed with kjb_print_error.
For successful return, "str" cannot contain two numbers. For example, it
can't be something like "1 2".
ss1i64, ss1i32, ss1i16
These macros can be used to force scanning of a certain integer size. The
argument of these is normally a pointer to kjb_int64, kjb_int32, or
kjb_int16 as appropriate.
This software is not adequatedly tested. It is recomended that
results are checked independantly where appropriate.
