pthread_kill - send a signal to a thread
SYNOPSIS
cc -mt [ flag... ] file... -lpthread [ library... ]
#include <signal.h>
#include <pthread.h>
int pthread_kill(pthread_t thread, int sig);
The pthread_kill() function sends the sig signal to the thread designated by thread. The thread argument must be a member of the same
process as the calling thread. The sig argument must be one of the signals listed in signal.h(3HEAD), with the exception of SIGCANCEL
being reserved and off limits to pthread_kill(). If sig is 0, a validity check is performed for the existence of the target thread; no
signal is sent.
Upon successful completion, the function returns a value of 0. Otherwise the function returns an error number. If the pthread_kill() func-
tion fails, no signal is sent.
The pthread_kill() function will fail if:
ESRCH No thread could be found corresponding to that specified by the given thread ID.
EINVAL The value of the sig argument is an invalid or unsupported signal number.

pthread_kill - send a signal to a thread
SYNOPSIS
#include <signal.h>
int pthread_kill(pthread_t thread, int sig);
Compile and link with -pthread.
DESCRIPTION
The pthread_kill() function sends the signal sig to thread, another thread in the same process as the caller. The signal is asynchronously
directed to thread.
If sig is 0, then no signal is sent, but error checking is still performed; this can be used to check for the existence of a thread ID.
RETURN VALUE
On success, pthread_kill() returns 0; on error, it returns an error number, and no signal is sent.
ERRORS
ESRCH No thread with the ID thread could be found.
EINVAL An invalid signal was specified.
CONFORMING TO
POSIX.1-2001.
NOTES
Signal dispositions are process-wide: if a signal handler is installed, the handler will be invoked in the thread thread, but if the dispo-
sition of the signal is "stop", "continue", or "terminate", this action will affect the whole process.

In sun solaris whenever a jvm crashes we used to get the core file generated in binary format. We convert this core file to human readable format using
