C语言 文件操作实现复制的功能

 使用二进制打开可以复制大型文件如：.exe文件，音频视频文件等。

#include 
#define MAXSIZE 4096
#define MAXPATH 1024
int main(int argc, char *argv[])
{

	if (argc != 3)
	{
		fprintf(stdout, "Usage: mycp sourcefile targetfile!\n");
		return -1;
	}
	if (strlen(argv[1]) > MAXPATH || strlen(argv[2] > MAXPATH))
	{
		fprintf(stdout, "FilePath is too long to copy!\n");
		return -2;
	}
	char sourcefilename[MAXPATH] = { 0 };
	char targetfilename[MAXPATH] = { 0 };
	
	char tmpBuf[4096] = { 0 };
	int n = 0;
	strcpy(sourcefilename, argv[1]);
	strcpy(targetfilename, argv[2]);
	FILE *fp1 = fopen(sourcefilename, "rb");
	FILE *fp2 = fopen(targetfilename, "wb");
	if (fp1 == NULL || fp2 == NULL)
	{
		printf("open a file error!\n");
	}
	int count = 0;
	while (/*!feof(fp1)*/(count = fread(tmpBuf, sizeof(char), MAXSIZE, fp1)))
	{
		//每次最多读4096个字节的内容
		fwrite(tmpBuf, sizeof(char), count, fp2);//把每次实际读到的数据写入目标文件
	}
	fclose(fp1);
	fclose(fp2);
	return 0;
	getchar();
}
