This is from a program I wrote over in 1998 that I am trying to compile on a linux machine:
void write_line (FILE *fp, int rec_no, line_rec *arec)
{
fpos_t woffset;
woffset = (rec_no - 1) * sizeof(line_rec);
fsetpos(fp,&woffset);
fwrite(arec,sizeof(line_rec),1,fp);
}On the line... (2 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)

NAME
SoXtClipboard -- Provides Inventor copy/paste support
INHERITS FROM
SoXtClipboard
SYNOPSIS
#include <Inventor/Xt/SoXtClipboard.h>
typedef void SoXtClipboardPasteCB(void *userData, SoPathList *pathList)
typedef void SoXtClipboardImportCB(void *userData, Atom dataType, void *data, uint32_t numBytes)
#define _XA_CLIPBOARD_ ((Atom) 0)
Methods from class SoXtClipboard:
SoXtClipboard(Widget w, Atom selectionAtom = _XA_CLIPBOARD_)
~SoXtClipboard()
void copy(SoNode *node, Time eventTime)
void copy(SoPath *path, Time eventTime)
void copy(SoPathList *pathList, Time eventTime)
void copy(Atom dataType, void *data, uint32_t numBytes, Time eventTime)
void paste(Time eventTime, SoXtClipboardPasteCB *pasteDoneFunc, void *userData = NULL)
void addPasteInterest(Atom dataType, SoXtClipboardImportCB *pasteImportFunc, void *userData = NULL)
DESCRIPTION
This class manages data transfers for copy and paste. Transfers may occur within the same process, or between different processes. This
uses the Xt selection mechanism to implement the ICCCM protocol for the transfer of data.
METHODS
SoXtClipboard(Widget w, Atom selectionAtom = _XA_CLIPBOARD_)
~SoXtClipboard()
Constructor and destructor. w is the Xt widget for which this clipboard acts as an agent. selectionAtom is the X selection through which
data should be transferred. For quick data transfers, this should be XA_PRIMARY. The default is _XA_CLIPBOARD_ which uses the X clip-
board selection.
void copy(SoNode *node, Time eventTime)
void copy(SoPath *path, Time eventTime)
void copy(SoPathList *pathList, Time eventTime)
This copies the passed scene graph object, and tells the X server that the clipboard now owns the selection which was specified by
selectionAtom in the constructor. When a paste happens (in this window, another window, or another process), the X server will ask this
clipboard for the data it copied here. The eventTime should be the time found in the X event structure which triggered the copy opera-
tion, and is used to ensure synchronization of copy and paste requests. Data targets supported for export are INVENTOR_2_1, INVEN-
TOR_2_1_FILE, INVENTOR_2_0, INVENTOR_2_0_FILE, VRML_1_0, VRML_1_0_FILE. Also exported for backwards compatibility are INVENTOR and
INVENTOR_FILE, which are equivalent to INVENTOR_2_0 and INVENTOR_2_0_FILE.
void copy(Atom dataType, void *data, uint32_t numBytes, Time eventTime)
This behaves like the above copy routines, but the data can be in any format as specified by dataType.
void paste(Time eventTime, SoXtClipboardPasteCB *pasteDoneFunc, void *userData = NULL)
This makes a request to the X server for data to paste from the selection atom specified in the constructor (selectionAtom), then
returns. When the data is retrieved from the selection owner, the pasteDoneFunc callback is invoked. The newly pasted data is passed as
the callback function's pathList argument (an SoPathList). Data targets supported for import are INVENTOR_2_1, INVENTOR_2_1_FILE, INVEN-
TOR_2_0, INVENTOR_2_0_FILE, VRML_1_0, VRML_1_0_FILE. Also imported for backwards compatibility are INVENTOR and INVENTOR_FILE, which
are equivalent to INVENTOR_2_0 and INVENTOR_2_0_FILE.
void addPasteInterest(Atom dataType, SoXtClipboardImportCB *pasteImportFunc, void *userData = NULL)
This extends the paste interest to recognize an additional target as specified by dataType. It can be called multiple times to register
interest in more than one extension. The pasteImportFunc will be called when data of the registered type is pasted. Passing NULL as the
pasteImportFunc will remove paste interest for that data type (even if the data type is one of the defaults). This should be called
before paste() so that paste() will accept pastes of data types that have been registered here. A dataType atom can be created with
XmInternAtom, e.g.: XmInternAtom(XtDisplay(widget),"INVENTOR",False);
