DESCRIPTION
This routine reads a short 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 a short (i.e., it is between SHORT_MIN and
SHORT_MAX), it sets *short_ptr to that number and returns NO_ERROR.
Otherwise and error message is set, and ERROR is returned. The contents of
*short_ptr are only changed on success.
RETURNS
If "str" represents a valid short, 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.
NOTE
For successful return, "str" cannot contain two numbers. For example, it
can't be something like "1 2".
MACROS
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.
DISCLAIMER
This software is not adequatedly tested. It is recomended that
results are checked independantly where appropriate.
