How to pass data in malloc array of one class to another class
-
Currently I am emitting the pointer to malloc array in a signal of class A. That signal is connected to SLOT of class B where the pointer is successfully received.
If i am deleting the pointer in ClassB, the data is not getting deleted. Which is leading to memory leak. -

malloc array
What is that?
Do you really use malloc() in a C++ application?!
Use "new" instead."If i am deleting the pointer in ClassB, the data is not getting deleted" - please show your code.

how are the slot AND the pointer-parameter declared? Please show EXACT declarations.
and...do you malloc the space or is it being allocated by a third party library that simply returns its address to you?

if You allocate memory with malloc, calloc or realloc you can't delete this memory. use free() to free the allocated Memory!
