基本多线程有问题

char * name; long i = 0; FILE * file; name =（char *）pvParam; printf（" Starting''％s''\ nn，quot; name）; file = fopen（name，" ; w"）; for（i = 0; i< 10000000; i ++） { fprintf（file， "％ld\\\" ;，i）; } fclose（文件）; return（dwResult）; } VOID主（VOID）{ int cnt; int redak [MAX_M]; char a1 [] =" a1"; char b1 [] =" b1"; char c1 [] =" ; c1" ;; char d1 [] =" d1" ;; HANDLE hThreads [MAX_M]; //处理线程 //查看CreateThread的原型 函数） DWORD dwThreadID [MAX_M]; //需要ID-s //创建线程1（0）查看参数 hThreads [0] = CreateThread（NULL，0，ThFunc，（PVOID）a1,0，& dwThreadID）; hThreads [1] = CreateThread（NULL，0，ThFunc，（PVOID）b1,0，& dwThreadID）; hThreads [2] = CreateThread（NULL，0，ThFunc，（ PVOID）c1,0，& dwThreadID）; hThreads [3] = CreateThread（NULL，0，ThFunc，（PVOID）d1,0，& dwThreadID）; //等到他们完成工作，等待INFINITE WaitForMultipleO bjects（MAX_M，hThreads，TRUE，INFINIT E）; //关闭线程句柄 for（cnt = 0; cnt< MAX_M; cnt ++）{ printf（" Closing thread％d .... \ n"，cnt）; CloseHandle（hThreads [cnt]）; } } 我希望我能帮到你，如果你对这个问题有更多的疑问 代码请发给我邮件。 最好的问候 Sinisa Try this.#include<stdio.h>#include<windows.h> #define MAX_M 4// define max file to open// thread functionDWORD WINAPI ThFunc(PVOID pvParam){DWORD dwResult = 0; char * name ;long i=0;FILE * file; name =( char*)pvParam; printf( "Starting ''%s''\n", name );file = fopen( name, "w" ); for ( i=0;i< 10000000;i++){fprintf( file, "%ld\n", i );}fclose(file); return(dwResult);} VOID main(VOID){ int cnt;int redak[MAX_M];char a1[]="a1";char b1[]="b1";char c1[]="c1";char d1[]="d1"; HANDLE hThreads[MAX_M];// handles to threads//see prototype of CreateThreadfunction)DWORD dwThreadID[MAX_M];// need for ID-s // create thread 1(0) see argumentshThreads[0] = CreateThread(NULL,0,ThFunc,(PVOID)a1,0,&dwThreadID );hThreads[1] = CreateThread(NULL,0,ThFunc,(PVOID)b1,0,&dwThreadID );hThreads[2] = CreateThread(NULL,0,ThFunc,(PVOID)c1,0,&dwThreadID );hThreads[3] = CreateThread(NULL,0,ThFunc,(PVOID)d1,0,&dwThreadID ); // wait until they finish their job , wait INFINITEWaitForMultipleObjects(MAX_M,hThreads,TRUE,INFINIT E); //closing handles to threadfor(cnt=0; cnt < MAX_M; cnt++){printf("Closing thread %d ....\n",cnt);CloseHandle(hThreads[cnt]);}}I hope I have helped you and if you have futher questions about thiscode send me them by mail.
