Error handling

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

typedef int32_t qmckl_exit_code;

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.
