Hi,

I am trying to debugg using gdb. I can able to debugg till thread creation i.e., pthread_create() .After this if i keep breakpoint at thread run function i.e., TempThread_RunFunction() its not hitting it shows. SIGTRAP trace/breakpoint trap.

Please help to solve this.

My main.c file is as follows.

#include <stdio.h>

#include <string.h>

#include <stdlib.h>

#include <pthread.h>

pthread_attr_t Thread_Attribute;

void *TempThread_RunFunction(void *inPtr)

{

int d =100;

printf("Function %s \t Line No %d \n",__FUNCTION__,__LINE__);

printf("In Thread d %d \n",d);

}

void main ()

{

pthread_attr_init(&Thread_Attribute);

int ret;

int stacksize;

pthread_t Tempthreadid;

ret = pthread_attr_setstacksize(&Thread_Attribute, 4*8192);

printf("pthread_attr_setstacksize ret %d \n",ret);

ret = pthread_attr_getstacksize (&Thread_Attribute, &stacksize);

printf("pthread_attr_getstacksize ret %d \n",ret);

printf("stack size1 = %li\n", stacksize);

pthread_create(&Tempthreadid, &Thread_Attribute, &TempThread_RunFunction, NULL );

while(1)

{

usleep(500000);

}
