I'm not really allocating an array of pointers like I think I am... How can I ensure that I really allocated what I think I did?? Sep15, 2012 at 5:01am ssrun (49) sizeof(tab_list) is a pointerso it will return 4 bytes as it's . I think you want to zero out max...
I mean, is there any other situation I should be careful of? I did some reading on both the ifort manual and the web, and it is my understanding that they are created not only when copying two arrays with pointers (see above) but also when passing a dynamic array made with pointer...

The article deals with using dynamic arrays in the C language. The way to handle dynamically scalable values in C is to manipulate pointers in a continuous way. From the C point of view, an array is nothing more than a block of memory that can be addressed as a group of elements of ...
C malloc() The name "malloc" stands for memory allocation. Themalloc()function reserves a block of memory of the specified number of bytes. And, it returns apointerofvoidwhich can be casted into pointers of any form. Syntax of malloc() ...
in the previous section ‘void pointers’ are used to reference the collection elements. Void pointers are pointers which point to some arbitrary data that has no specific type. As a consequence you are unable to directly deference a pointer of this type and must first provide a casting type....

12.1. Dynamic Memory and Smart Pointers In C++, dynamic memory is managed through a pair of operators: new, which allocates, and optionally initializes, an object in dynamic memory and returns a pointer to that object; and delete, which takes a pointer to a dynamic object, destroys that ob...
