named pipe in native code?

[zeeshan]

HI Dear,

i am trying to create a named pipe in my native code which i will
access in my java code
here is my sample code to create piple which doesn't work

---------------------------------------------------------------------------
#include <string.h>
#include <jni.h>
#include <unistd.h>
#include <sys/types.h>
#include <stdio.h>
#include <unistd.h>

/* This is a trivial JNI example where we use a native method
* to return a new VM String. See the corresponding Java source
* file located at:
*
* apps/samples/hello-jni/project/src/com/example/HelloJni/
HelloJni.java
*/
jstring
Java_com_example_hellojni_HelloJni_stringFromJNI( JNIEnv* env,
jobject thiz )
{

// mkfifo(const char* path, mode_t mode);
mkfifo("test_fifo", S_IRUSR );
return (*env)->NewStringUTF(env, "Hello JNI !");
}

------------------------------------------------------------------------------------

i have configured cygwin make with my eclipse and when it compiles
this program it gives me error at mkfifo as it doesn't know s_IRUSR

could anybody help me to figure out what is the problem and how can i
solve it

Please do not cross-post.

You are missing a #include <sys/stat.h> I believe.
