使用Windows

所以我从二进制文件中读取一个unsigned int数据值列表.该文件包含按顺序列出的许多数据集.这是从char*中读取单个数据集的函数,指向它的开头:

function read_dataset(char* stream, t_dataset *dataset){

    //...some init, including setting dataset->size;

    for(i=0;i<dataset->size;i++){
        dataset->samples[i] = *((unsigned int *) stream);
        stream += sizeof(unsigned int);
    }
    //...
}

read_dataset在这样的上下文中:

//...
char buff[10000];
t_dataset* dataset = malloc( sizeof( *dataset) );
unsigned long offset = 0;

for(i=0;i<number_of_datasets; i++){

    fseek(fd_in, offset, SEEK_SET);

    if( (n = fread(buff, sizeof(char), sizeof(*dataset), fd_in)) != sizeof(*dataset) ){
        break;
    }

    read_dataset(buff, *dataset);

    // Do something with dataset here.  It's screwed up before this, I checked.


    offset += profileSize;
}
//... …
