I would like to create shared library(.dll) form java code with graalVM. When I use the shared library which is created from java code by native-image, the execution result has succeeded or failed depending on the execution environment.
When the execution result fails, graal_create_isolate fuction return 23. I would like to know how to look up the meaning of this 23 meaning.

The generated header(graal_isolate.h) by native-image command says “a non-zero value on failure.”, but the meaning of each value is not written in that header. Please could someone help me? thanks a lot.

[excecution environment and result]

• Windows Server 2022(version: 21H2, OS build: 20348.197)
  result: error
• Windows Server 2022(version: 21H2, OS build: 20348.469)
  result: success
• Windows Server 2022(version: 21H2, OS build: 20348.2227)
  result: error
• Windows 10 Enterprise(version: 22H2, OS build: 19045.4412)
  result: success

[execution result]

• success
  main.exe
  count = 1234
• error
  main.exe
  initialization error(ret = 23)

• main.c

int main(void) {
  graal_isolate_t *isolate = NULL;
  graal_isolatethread_t *thread = NULL;
  int ret = graal_create_isolate(NULL, &isolate, &thread);
  if (ret != 0) {
    fprintf(stderr, "initialization error(ret = %d)n", ret);
    return -1;
  }
  printf("count = %dn", getCount(thread));
  if (graal_tear_down_isolate(thread) != 0) {
    fprintf(stderr, "shutdown error(ret = %d)n", ret);
    return -1;

  return 0;
}

[build environment]

• GraalVM
  graalvm-jdk-17.0.11+7.1
• Vidual Studio
  Visual Studio 2022
  cl –version
  Microsoft(R) C/C++ Optimizing Compiler Version 19.36.32535 for x64

My expectation is that it will work in any environment.
