unsigned long *ulong_ptr
);
DESCRIPTION
This routine reads an unsigned long 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 unsigned long it sets *unsigned
long_ptr to that number and returns NO_ERROR. Otherwise and error message is
set, and ERROR is returned. The contents of *unsigned long_ptr are only
changed on success.
RETURNS
If "str" represents a valid long, 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
ss1u64, ss1u32, ss1u16
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.
