各位，我的目的是获取调用其他程序hello.exe输出的信息。网上查找一下代码，但是实现不了！！
为什么呢？
我选择用LCC-win32为编译器。
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <windows.h>
int main(int argc,char *argv[])
{
SECURITY_ATTRIBUTES sa;
sa.nLength=sizeof(SECURITY_ATTRIBUTES);
sa.lpSecurityDescriptor=NULL;
sa.bInheritHandle=TRUE;
HANDLE outHandle;
outHandle = CreateFile("aa.txt",GENERIC_READ|GENERIC_WRITE,FILE_SHARE_READ|FILE_SHARE_WRITE,&sa,CREATE_ALWAYS,0,NULL);
PROCESS_INFORMATION processInfo;
STARTUPINFO startUpInfo;
memset(&startUpInfo, 0, sizeof(STARTUPINFO));
memset(&processInfo ,0, sizeof(PROCESS_INFORMATION));
startUpInfo.cb = sizeof(STARTUPINFO);
startUpInfo.dwFlags = STARTF_USESTDHANDLES;
startUpInfo.wShowWindow=SW_SHOWNORMAL;
startUpInfo.hStdOutput = outHandle;
if(!CreateProcess("hello.exe",NULL, NULL, NULL, FALSE,
CREATE_NEW_CONSOLE, NULL, NULL,
&startUpInfo, &processInfo)){
CloseHandle(outHandle);
printf("open hello.exe error");
}else{
DWORD filesize=1000;
char * buffer = malloc(filesize + 1);
memset(buffer, 0, filesize+1);
DWORD readsize;
ReadFile(outHandle,buffer,filesize,&readsize,NULL);
printf("%s\n",buffer);
free(buffer);
WaitForSingleObject(processInfo.hProcess,INFINITE);
printf("open hello.exe ok");
CloseHandle(outHandle);
CloseHandle(processInfo.hProcess);
CloseHandle(processInfo.hThread);
}
return 0;
}
