What is wrong with using feof() to control a read loop? For example: #include <stdio.h> #include <stdlib.h> int main(int argc, char **argv) { char *path = "stdin"; FILE *fp...

I opened a file, the stream is found at the address of pointer ptr. I am attempting to see whether or not a file is blank. Using the following if (fgetc(ptr) != EOF) works as expected. When the ...

Upon looking at the ISO C11 standard for fgets §7.21.7.2, 3, the return value is stated regarding the synopsis code: #include <stdio.h> char *fgets(char* restrict s, int n, FILE* restrict str...

I'm a beginner in C++ and trying to better understand feof(). I've read that feof() flag is set to true only after trying to read past the end of a file so many times beginners will read once more ...

I am writing a C library that reads a file into memory. It skips the first 54 bytes of the file (header) and then reads the remainder as data. I use fseek to determine the length of the file, and t...

I've written this minishell but I'm not sure I'm making a correct control of the errors. I know fgets can return feof and ferror (http://www.manpagez.com/man/3/fgets/) but I don't know how to...

I am encoutering this problem. I am using while loop to scan string of numbers and need to end scanning and start proceeding the rest of my program. I just can't figure out, how to flush the stdin ...

Does feof() checks for eof for the current position of filepointer or checks for the position next to current filepointer? Thanks for your help !

I need to input coordinates into an array until EOF is encountered, but something is wrong in my code. I used ctrl+Z, ctrl+D int main() { int x[1000],y[1000]; int n=0,nr=0,a,b,i; printf("Enter ...

Here is the code that I am using: if (!($fp = fsockopen('ssl://imap.gmail.com', '993', $errno, $errstr, 15))) echo "Could not connect to host"; $server_response = fread($fp, 256); echo $server_re...

I come from a C and C++ background but also play with some web stuff. All us C folks (hopefully) know that calling feof on a FILE* before doing a read is an error. This is something that stings new...

On another question, Jerry Coffin pointed out the following: It's (probably) not really related to your question, but while (!feof(fileptr)){ is pretty much a guaranteed bug. I figured I would...
