32: These two functions are dynamic versions of <CODE>strcpy</CODE> and
33: <CODE>strcat</CODE>. They use <CODE>malloc</CODE> for allocating space
34: for the string. If <CODE>StrAllocCopy</CODE> is called with a non-NULL
35: dest, then this is freed before the new value is assigned so that only
36: the <EM>last</EM> string created has to be freed by the user. If
37: <CODE>StrAllocCat</CODE> is called with a NULL pointer as destination
38: then it is equivalent to <CODE>StrAllocCopy</CODE>.

61:
62: <DL>
63: <DT>tmpl
64: <DD>is a template string to match the name against. agaist, may
65: contain a single wildcard character * which matches zero or more
66: arbitrary characters.
67: <DT>name
68: <DD>is the name to be matched agaist the template.
69: </DL>
70:
2.26 frystyk 71: Returns empty string ("") if perfect match, pointer to part matched by
72: wildcard if any, or NULL if no match. This is basically the same as
73: YES if match, else NO.
