[antonio1980]

hi,

i have this C code program to create thread:

double dwThreadId1;
CreateThread (NULL,
0,
(LPTHREAD_START_ROUTINE)&ThreadParam,
0,
&dwThreadId1,
);

when compiling, i receive these wornings and errors:

warning: implicit declaration of function 'CreatThread'
error: 'LPTHREAD_START_ROUTINE' undeclared(first use in this function)
error:'LPVOID' undeclared (first use in this function)


could anyone help me to resolve this problem ??

Regards.

CreateThread is a windows function.

On linux you need to use pthreads:

 
#include <pthread.h>
 
pthread_t thread;
double threadid;
pthread_create(&thread,NULL,ThreadParam,&threadid);

You will also need to change the definition of ThreadParam from probably

DWORD WINAPI ThreadParam(LPVOID *)

to

void *ThreadParam(void *param)

.
