The printf , fprintf , dprintf , and asprintf functions may fail due to an underlying malloc 3C failure if: If anyone has the similar problem before and knows the solution, please help me out here. Not doing so can cause incorrect behavior. So when using Sun compilers or the Sun linker, you must supply either the -mt or the -lthread options. Check all use of malloc, free, pointers, arrays, data sizes etc. If you are using another compiler, check its documentation to ensure that it produces code that meets this requirement. For example, an engineer who was unfamiliar with the application ported lines of C code in approximately two days.

In this instance, NMI was only lightly used, but the uses were widely distributed. All of them call the same include to open the socket, and all are successful when we run the application on Solaris The value of errno shall be defined only after a call to a function for which it is explicitly stated to be set and until it is changed by the next function call or if the application assigns it a value.
Making the Transition From NMI to JNI
The exact same libraries and executables will work on both servers, right up until the jni socket call is made. Sign up or log in Sign up using Google. JNI does not require header information or stub files. You must release the array elements quickly after you jbi them. Errors For the conditions under which printffprintfand dprintf solaaris fail and may fail, refer to fputc 3C or fputwc 3C.
Native mni using JNI should not modify the signal-processing state. Email Required, but never shown. We have disabled IPv6 on the server, as we thought perhaps java was trying to force this protocol, but this didn’t make a difference either. You must specify the libthread. For example, an engineer who was unfamiliar with the application ported lines of C code in approximately two days. For more information, see:.
JNI/C socket connection error on Solaris 11 – Stack Overflow
But without a complete example that can be used to duplicate your problem, it’s impossible to tell. You cannot call other JNI operations.
Ok, I removed the fprintf statements, but I still have the same result. This problem does not exist on either Solaris 7 software or Solaris 8 software. Additionally, the frame pointer register must always point to a valid stack frame.
If you are using Solaris 2.
I’ve added output to see what exactly is being sent to the connect call and it looks like the call is getting everything it needs:. The printffprintfdprintfand asprintf functions may fail due to an underlying malloc 3C failure if:.
Check all use of malloc, free, pointers, arrays, data sizes etc. Applets cannot be affected by a change in native method support. You have likely overwritten the bounds of something.
The failure is around socket connect at or soon after that. The VM relies on the ability to examine the stack frames of functions on a thread’s stack. C programs use the generated header and source files to reference instance variables solariw an object from native source code. If anyone has the similar problem before and knows the solution, please help me out here.
Making the Transition From NMI to JNI (Java 2 SDK for Solaris Developer’s Guide)
The Sun C compiler option -mt automatically adds the -lthread option, and the -lc option is typically not specified it defaults to the end of the list. The reason is one function call in native codesay Acalls Bto create a client socket, ini B return a wraper struct pointer of that socket, but in Athis pointer is always NULL.
