The C library fseek (FILE *stream, long int offset, int whence) function sets the file position of the stream to the given offset.This function is a part of the C Standard Library and is used for file handling.

On streams open for update (read+write), a call to fseek allows to switch between reading and writing. Parameters stream Pointer to a FILE object that identifies the stream. offset Binary files: Number of …

Definition and Usage The fseek() function moves the position indicator to a specified position in the file. The fseek() function is defined in the <stdio.h> header file.

Dec 5, 2024 · Sets the file position indicator for the file stream stream to the value pointed to by offset . If the stream is open in binary mode, the new position is exactly offset bytes measured from the …

POSIX also requires that fseek first performs std::fflush if there are any unwritten data (but whether the shift state is restored is implementation-defined). The standard C++ file streams guarantee both …
