关于在c++中使用sigaction函数的问题....................

lizhenjia

代码如下:
int genTool::initDaemon(const char *pathname, int issetworkpath)
{
   struct sigaction act, sa;
   act.sa_handler = signalProcess;//函数句柄
  .......
}

int genTool::installSignal()
{
.................
}
installSignal,initDaemon都是类genTool的成员函数,现在的问题是编译报:
"genTool.cpp", line 208.26: 1540-0286 (W) The unqualified member "signalProcess" should be qualified
with "::" and preceded by an "&" when forming an expression with type pointer-to-member.
"genTool.cpp", line 208.26: 1540-0216 (S) An expression of type "void (genTool::*)(int)" cannot be c
onverted to "extern "C" void (*)(int)".

请问在act.sa_handler = signalProcess这句中该如何写呢？

yuxq

act.sa_handler = (void (*)())signalProcess;//

我改成：
(void (*)(int))signalProcess
但还是提示:
"genTool.cpp", line 264.39: 1540-0216 (W) An expression of type "void (genTool::*)(int)" cannot be c
onverted to "void (*)(int)".
"genTool.cpp", line 264.39: 1540-0286 (W) The unqualified member "signalProcess" should be qualified
with "::" and preceded by an "&" when forming an expression with type pointer-to-member.

没人碰到过类似的问题吗？

看看你signalProcess怎么写的？

另外如果不长，代码贴出来看看
