It is similar to a string comparison (for string sorting) but unlike
the usual strncmp() or
strncasecmp() functions, when digits are encountered in a string, they are
converted to a number and
this is the number value which is taken in account for comparison.
This is especially useful to sort component references or value.
For instance:
when the 2 strings U12 and U2 are compared by ASCII value:
In usual comparison (from ASCII value), U120 is sorted before U20
In StrNumCmp:
120 is read as a integer value
20 is read as a integer value
and comparisons are between U<120> and U<20> where <120> and <20> are integers,
not chars.
and U120 is sorted after U20
Hello Jean-Pierre,
thank you for the information.
So a numeric character range is to be treated as one character position
whose value its the parsed number, right?
Is the aLength parameter designed to mean raw character counts, or
character/number positions? Would "U12" compare smaller to "U2" at
aLength == 2?
Cases like "U12A4A3" vs. "U12A4A4" are also specified where the latter
would compare "greater", yes?
Michael
