How to get current thread id in android ndk?

[Riasat Abir]

Hi,

How can I get the current thread id in android ndk?

This is used for linux: pid_t tid = syscall(SYS_gettid);

will it be serve the same purpose for android: pid_t  gettid(void); //defined in unistd.h 

Thanks,

Riasat

I used to test a sample C++, and get thread id by the function pthread_self(). Its from C++, then I port to Java using NDK.

 

It returned the id, although I didn’t check if it was right or wrong, J. U should try that?

gettid() is defined in <unistd.h> in Bionic.

The function isn't defined in GLibc for some odd reason.

pthread_self() will not return the kernel thread id, but something else corresponding to the pthread implementation.

They should not be confused.
