See "info libc alpha ftell".

This is where a search program comes in handy. Eg:

   e:\djgpp\src\libc> grep fseek .../*.c

gives the results:

   ansi/stdio/filbuf.c:   we read here, and reset it to 512 ...
   ansi/stdio/fseek.c:fseek(FILE *f, long offset, int ptrname)
   ansi/stdio/fsetpos.c:    fseek(stream, (long)(*pos), SEEK_SET);

For the FILE structure, check the headers in the include directory
(it is in stdio.h).
