Auto-testing for memory leaks.
|
| |
Hello, I have a bunch of derived types that contain pointer arrays. In the course of their use the structures get allocated, copied, destroyed, reallocated, extended, etc. I test for memory leaks in a rather brain dead way - I call the routines in my test code many 10's of 1000's of times with top running in another window so I can keep an eye on... more »

How to make a function work with different type and kind type argument
|
| |
Hi, the intrinsic sin(x), cos(x), etc, work with arguments of general type and kind type. Suppose I want to write a function mysin(x) which just calls sin(x) and, like sin(x), must work with general type and kind type argument. I can achieve the generality of type through overloading, however how can I obtain generality of kind type?... more »

| |
Dear all, Though this is a mixed language issue, I did decide to post here, How can I can wrap a fortran function in C++? I am aware of extern linkage and the _ issues that have to be added. If I would like to wrap this, what should be done? extern "C" { void lapackfunctiontocall_(...) ...I can make an extern "C" block in a header file and put all needed... more »

array constructor syntax

Since the following code is only accepted by g95 and not by gfortran-4.2.3 or the intel compiler 10.1, I was wondering if I got the syntax right. module array_constructor implicit none character(len=14), dimension(5), parameter :: & var_names = [character(len=14) :: & 'YEAR', 'COMPCODE', 'RECEPTYPE', 'NCOLS', 'NROWS']... more »
