The library should never make the calling programs abort, nor
|
|
perform any input/output operations. This decision has to be taken
|
|
by the developer of the code calling the library.
|
|
|
|
All the functions return with an exit code, defined as
|
|
#+NAME: type-exit-code
|
|
#+begin_src c :comments org :tangle (eval h_type)
|
|
typedef int32_t qmckl_exit_code;
|
|
#+end_src
|
|
|
|
|
|
#+begin_src f90 :comments org :tangle (eval fh_type) :exports none
|
|
integer , parameter :: qmckl_exit_code = c_int32_t
|
|
#+end_src
|
|
|
|
The exit code returns the completion status of the function to the
|
|
calling program. When a function call completed successfully,
|
|
~QMCKL_SUCCESS~ is returned. If one of the functions of
|
|
the library fails to complete the requested task, an appropriate
|
|
error code is returned to the program.
|
|
|
|
Here is the complete list of exit codes.

* Failing
|
|
|
|
To make a function fail, the ~qmckl_failwith~ function should be
|
|
called, such that information about the failure is stored in
|
|
the context. The desired exit code is given as an argument, as
|
|
well as the name of the function and an error message. If the
|
|
message is ~NULL~, then the default message obtained by ~qmckl_string_of_error~ is used. The return code of the function is
|
|
the desired return code.
|
|
Upon failure, a ~QMCKL_NULL_CONTEXT~ is returned.
