[aspectc-user] RE: aspectc-user Digest, Vol 4, Issue 4

Hy Olaf, 

Thank u for your response ! 

Ok maybe i don't have to change New operator Comportement, but supposed that i need to find a number line and the file name of a method X, how can i do it with Aspect ??

Because i'm developing a memory debugger and i need this kind of informations ..

maybe the problem is a litlle bit dificult, but i find the solution without aspect..we have just to modle it with aspect no ?

i want just change a comportement of new/X/Y.. and add him in a new definition tow news arguments (__LINE__//__FILE__)

ok i can ask my problem in the ather form:

If i want detect the number LINE and name FILE of the method main , how can i do ?

thak u for your time, Heni
