If it is successful, the fseek() function return 0, otherwise the function returns a nonzero value. whence provides the offset bytes from the file location. whence must be one of the values 0, 1, or 2 which represent three symbolic constants (defined in stdio.h) as follows: Constants whence File location SEEK_SET 0 File beginning

In this c++ Video tutorial, you will learn the use of get and put position indicators available. You will learn how to get/check the get and put position indicators using tellg() and tellp fread() is an I/O function which is used to read the specified number of objects, of the "size" from a specified stream and places them in an array. This function returns the Are you sure that the first byte of the file isn't 0? I ask this because according to the binary resource data the icon resources have a NEWHEADER structure first. As far as I'm aware, and some random internet searches, the icon file format is the same. 12.5.1 rewind??. ????FILE *fp?,??????????char *_nextc,?????????????? typedef struct Input and output are normally sequential: each read or write takes place at a position in the file right after the previous one. When necessary, however, a file can be read or written in any arbitrary order. The system call lseek provides a way to move around in a file without reading or writing any data: From a given file (e.g. input.txt) read the alternate nth byte and write it on another file with the help of "lseek". lseek (C System Call): lseek is a system call that is used to change the location of the read/write pointer of a file descriptor. The location can be set either in absolute or While not necessarily the most popular method, I've heard that the ftell, fseek method may not always give accurate results in some circumstances. Specifically, if an already opened file is used and the size needs to be worked out on that and it happens to be opened as a text file, then it's going to give out wrong answers. Name SEEK_END macro
