fseek is a C function belonging to the ANSI C standard library, and included in the file stdio. h. Its purpose is to change the file position indicator for the specified stream. Because fseek uses 32 bit values on many platforms it has a limitation of maximum 2 gigabyte seeks. fseeko64 would be used for larger offsets.

The -fPIC option tells the compiler to generate position-independent code (i.e. code that can be loaded at any particular virtual memory address at runtime). ... Others (like x86) don't, but it's still useful to use -fPIC since position-dependent memory references can't be shared by different processes and thus are copied.

The C library function int fprintf(FILE *stream, const char *format, ...) sends formatted output to a stream.

The fscanf() function is used to read formatted input from the file. It works just like scanf() function but instead of reading data from the standard input it reads the data from the file. ... On success, this function returns the number of values read and on error or end of the file it returns EOF or -1 .

int fflush(FILE *ostream); ostream points to an output stream or an update stream in which the most recent operation was not input, the fflush function causes any unwritten data for that stream to be delivered to the host environment to be written to the file; otherwise, the behavior is undefined.

Description. example. fseek( fileID , offset , origin ) sets the file position indicator offset bytes from origin in the specified file. status = fseek(___) returns 0 when the operation is successful. Otherwise, fseek returns -1 .

The fseek() function is used to set the file position indicator for the stream to a new position. This function accepts three arguments. The first argument is the FILE stream pointer returned by the fopen() function.

fseek(3) - Linux man page The fseek() function sets the file position indicator for the stream pointed to by stream. ... A successful call to the fseek() function clears the end-of-file indicator for the stream and undoes any effects of the ungetc(3) function on the same stream.

DESCRIPTION. The fdopen() function associates a stream with a file descriptor. File descriptors are obtained from open(), dup(), creat(), or pipe(), which open files but do not return pointers to a FILE structure stream. Streams are necessary input for almost all of the stdio library routines.
