Description

Under Linux, the same rules for pattern apply as those that apply for Linux command lines for addressing files: These rules can be retrieved by using "man 5 regexp" on Linux computers.
Example
The function checks the pattern "*a" for the following strings: "abc", "cdea", "abcd", "cdeafgh", "bbacc", "xyz".
main()
{
string pattern;
dyn_string ds1, ds2;
pattern = "*a";
ds1 = makeDynString("abc", "cdea", "abcd", "cdeafgh", "bbacc",
"xyz");
ds2 = dynPatternMatch(pattern, ds1);
DebugN("The pattern is valid for: " + ds2); //Return value is
"cdea"
}The function checks the pattern "?y?" in the following strings: "abc", "cdea", "abcd", "cdeafgh", "bbacc", "xyz".
main()
{
string pattern;
dyn_string ds1, ds2;
pattern = "?y?";
ds1 = makeDynString("abc", "cdea", "abcd", "cdeafgh", "bbacc",
"xyz");
ds2 = dynPatternMatch(pattern, ds1);
DebugN("The pattern is valid for: " + ds2); //Return value is
