thread wrapper

 最近做了一套thread wrapper， 可以以线程的形式运行任意函数, 例子如下：

#ifdef  _PTHREAD
#include <pthread.h>
void* thread_func_g(void*p){
 funcInfo_t* ft = (funcInfo_t*)p;
 __asm__(
 "subl %%ecx, %%esp\n"
 "movl %%esp, %%edi\n"
 "rep movsb\n"
 "call *%%eax\n"
 :
 :"a"(ft->f),"c"(ft->argSize), "S"(ft->esp)
 :"%edi");
}
#else
#endif

typedef struct{
 void* f;
 int argSize;
 char esp[128];
}funcInfo_t;

funcInfo_t global_funcInfo;
#define launchTemplateThread() \
create_thread(thread_func_g, &global_funcInfo);// /*thread_func_g(&global_funcInfo);*/

///////////////////// 3 args ////////////////////////////////////////////
#define slaunchArg3( a00, a01, a02) {char* pcur= global_funcInfo.esp; \
 (*(__typeof__(a00)*)pcur)=a00; pcur += _INTSIZEOF(__typeof__(a00));\
 (*(__typeof__(a01)*)pcur)=a01; pcur += _INTSIZEOF(__typeof__(a01));\
 (*(__typeof__(a02)*)pcur)=a02; pcur += _INTSIZEOF(__typeof__(a02));\
 global_funcInfo.argSize = pcur - global_funcInfo.esp;\
}\
launchTemplateThread();

#define slaunch3(sfunc) global_funcInfo.f = (void*) sfunc; slaunchArg3

#define kernel_ret  void* __attribute__((stdcall))

kernel_ret foo(int a, int b, int c){
printf("%d %d %d\n", a, b,c);
return 0;
} 

int main(){
int a, b, c;
char cc;
slaunch3(foo)(a, b, c);        // 产生一个线程
slaunch3(foo)(a, b, (int)c); // 产生一个线程
}

不知道这种发射多线程的方法会给大家带来方便吗？请各位大侠给点意见。
