Hi in my project I've to read a .bin file which has sensor data in the form of short(16 bit values) . I'm doing this using fread function into a buffer, but I feel that the reading-in is not happening correctly. I mean there is no consistence between what I write and what I read in. Can you guys suggest what is going wrong here? This is not my code from my project... I'm only trying to verify the fread and fwrite functions here. #include<stdio.h> void main() { FILE *fp = NULL; short x[10] = {1,2,3,4,5,6,5000,6,-10,11}; short result[10]; fp=fopen("c:\\temp.bin", "wb"); if(fp != NULL) { fwrite(x

Right now I don't store any logs, so if any script fails to load, I won't know it till I see results - and even when I notice that results are not correct, I can't do anything since I don't know which script failed. I've decided to store logs, but I am still not sure how to do it. So, my question is - what's more efficient - storing logs in sql database or files? I can create 'logs' table in my mysql database and store each log in separate row, or I can just use php's file_put_contents or fopen

I used to use the code below to Write an 1D array to a File: FILE *fp; float floatValue[5] = { 1.1F, 2.2F, 3.3F, 4.4F, 5.5F }; int i; if((fp=fopen("test", "wb"))==NULL) { printf("Cannot open file.\n"); } if(fwrite(floatValue, sizeof(float), 5, fp) != 5) printf("File write error."); fclose(fp); /* read the values */ if((fp=fopen("test", "rb"))==NULL) { printf("Cannot open file.\n"); } if(fread(floatValue, sizeof(float), 5, fp) != 5) { if(feof(fp)) printf("Premature end of file."); else printf("File read error."); } fclose(fp); for(i=0; i<5; i++) printf("%f ", floatValue[i]); My question is if i

I'm trying to write a Json object (JsonExport) and I'd like to write its content into a text file. I'm using max4live to export data from Audio DAW to Json in order to export to a server, but after that I would like to see the whole Json Object in a text file: var txtFile = "test.txt"; var file = new File(txtFile); var str = JSON.stringify(JsonExport); file.open("write"); // open file with write access file.write(str); file.close(); The compiler runs with no error, but i can not get the text file. I have used as well path to some of my directories and nothing. Any idea what's happening? Thanks

fwrite() 二进制安全 end条件[string写完/length-1]; fputs() fwrite()的别名; fread() 二进制安全,end条件[一个可用包/EOF/length-1/超时]; fgets() 读一行,end条件[换行符/EOF/length-1/超时],length默认1024; feof() 遇到[EOF/出错]才返回true; 文章来源: php socket 编程读写函数

1.memcpy 原型：void *memcpy(void*dest, const void *src, size_t n); （1）memcpy用来做内存拷贝，你可以拿它拷贝任何数据类型的对象，可以指定拷贝的数据长度； （2）将s中第14个字符开始的4个连续字符复制到d中。(从0开始) char * s="Golden Global View"; 　　char d[20]; memcpy(d,s+14,4);//从第14个字符(V)开始复制，连续复制4个字符(View) （3）如果目标数组destin本身已有数据，执行memcpy（）后，将覆盖原有数据（最多覆盖n）。如果要追加数据，则每次执行memcpy后，要将目标数组地址增加到你要追加数据的地址。 2. fopen 函数原型:FILE * fopen(const char * path, const char * mode); （1）返回值：文件顺利打开后，指向该流的文件指针就会被返回。如果文件打开失败则返回 NULL，并把错误代码存在error中。 （2）一般而言，打开文件后会做一些文件读取或写入的动作，若打开文件失败，接下来的读写动作也无法顺利进行，所以一般在 fopen() 后作错误判断及处理。 （3）参数说明：参数 path字符串包含欲打开的文件路径及文件名，参数 mode 字符串则代表着流形态。 （4）举例

My last question wasn't explained very well. What I'm trying to do here is insert data into a PHP File, Using the fwrite feature on another .php file. To keep this simple, I'm labelling the one I want data inserted as file.php and the one I'm using fwrite to execute on, is edit.php Now, I got the writing thing down, what my problem is, is I need to INSERT that data, Before the closing php tag on file.php. What I tried doing was, deleting the closing php tag, writing the data, and then rewriting the tag. Here is my source code for that: <?php $rows = file("file.php"); $tagremove = "?>"; foreach
