The fgets() function is a powerful and versatile tool for reading data in C. It is simple to use, safe, and adaptable. However, it is important to understand its limitations and use it carefully to avoid common errors. You can use fgets() effectively and write robust C programs by adher...
fgets()The function fgets() is used to read the string till the new line character. It checks array bound and it is safe too.Here is the syntax of fgets() in C language,char *fgets(char *string, int value, FILE *stream)Here,string − This is a pointer to the array of char....
gets() 从标准输入(stdin)读取字符,并将它们作为C字符串存储到str中,直到到达换行符或文件末尾。 用法: char * gets ( char * str );str:Pointer to a block of memory (array of char) where the string read is copied as a C string.returns:the function returns str 使用不安全,因为它不检查数组绑...

language. Therefore, I suggest making another function that won't be giving existing applications newline characters they didn't have before; or else having a variable that you set to make fgets() return newlines like it should. This is actually vers. 5.4.15. ...
What can I use instead of fgets in C? A possible alternative to fgets would be the getline() function. It is written in the form:str.getline(buffer, size, stdin).The buffer tracks the first position of a character, the size is a variable address that holds the input buffer, and stdin...
function safe_feof($fp, &$start = NULL) { $start = microtime(true); return feof($fp);}/* $fp 的赋值是由之前 fsockopen() 打开 */$start = NULL;$timeout = ini_get('default_socket_timeout');while(!safe_feof($fp, $start) && (microtime(true) - $start) < $timeout){ /* ...
