Hi all,
Can anyone tell me a little about the datatype FILE, which represents stream. What does its structure look like, and in which header file is it defined and so on...
Ex :
FILE *fp ;
fp = fopen("filename", "w") ; (6 Replies)
I am writing some code to do analysis on the file system (HP-UX 11.11).
I am using stat(..) to get file information. My problem is that the file-size may exceed the data types defined in 'sys/stat.h' & 'sys/types.h' respectively.
Thus file-sizes in the Giga-byte range are not read correctly.... (2 Replies)

Hello,everyone here.
I'm coding with KSH to achieve exploring the disk space and judging whether it closes to overflow.But It seems that no one way to convert a string variable to integer.

Can I convert L to integer type?

I am using perl 5.8.0.
I need to check some values to see it they are floats. Our system does not have Data::Types so I can't use is_float. Is there something else that I can use? The only thing in Data is Dump.pm. I am not allowed to download anything to our system so I have to use what I have.... (3 Replies)

fsetpos
FSEEK(3) Linux Programmer's Manual FSEEK(3)NAME
fgetpos, fseek, fsetpos, ftell, rewind - reposition a stream
SYNOPSIS
#include <stdio.h>
int fseek(FILE *stream, long offset, int whence);
long ftell(FILE *stream);
void rewind(FILE *stream);
int fgetpos(FILE *stream, fpos_t *pos);
int fsetpos(FILE *stream, fpos_t *pos);
DESCRIPTION
The fseek() function sets the file position indicator for the stream pointed to by stream. The new position, measured in bytes, is
obtained by adding offset bytes to the position specified by whence. If whence is set to SEEK_SET, SEEK_CUR, or SEEK_END, the offset is
relative to the start of the file, the current position indicator, or end-of-file, respectively. 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.
The ftell() function obtains the current value of the file position indicator for the stream pointed to by stream.
The rewind() function sets the file position indicator for the stream pointed to by stream to the beginning of the file. It is equivalent
to:
(void) fseek(stream, 0L, SEEK_SET)
except that the error indicator for the stream is also cleared (see clearerr(3)).
The fgetpos() and fsetpos() functions are alternate interfaces equivalent to ftell() and fseek() (with whence set to SEEK_SET), setting and
storing the current value of the file offset into or from the object referenced by pos. On some non-UNIX systems, an fpos_t object may be
a complex object and these routines may be the only way to portably reposition a text stream.
RETURN VALUE
The rewind() function returns no value. Upon successful completion, fgetpos(), fseek(), fsetpos() return 0, and ftell() returns the cur-
rent offset. Otherwise, -1 is returned and errno is set to indicate the error.
ERRORS
EBADF The stream specified is not a seekable stream.
EINVAL The whence argument to fseek() was not SEEK_SET, SEEK_END, or SEEK_CUR.
The functions fgetpos(), fseek(), fsetpos(), and ftell() may also fail and set errno for any of the errors specified for the routines
fflush(3), fstat(2), lseek(2), and malloc(3).
