| Summary | 0024079: stepread_setinput() opens file with exclusive read lock on Windows |
| Description | The function stepread_setinput() in stepread.c uses the C function fopen(). This is a problem for multi-threaded/multi-process applications on Windows, since the fopen() call will fail if another thread is in the process of opening the same file. Changing this call to use _fsopen() or _wfsopen() in Windows will allow multiple threads and processes to read the same STEP file. |
| Steps To Reproduce | Have two processes open the same STEP file simultaneously. |
