Behavior of ifstream::read() in g++
This program has different behavior in
* g++ 3.4.4 (Cygwin)
* gpp 4.0.1 *Djgpp)
* Microsoft C++ 13.00.9466
--- foo.cpp --
#include
#include
#include
using namespace std;
#define BUFFER_SIZE 1500
#define INPUT_FILE_NAME "in.txt"
void foo ()
{
char cbuffer[BUFFER_SIZE];
ifstream fs (INPUT_FILE_NAME);
fs.clear();
fs.seekg (0, ios::beg);
while (!fs.eof())
{
fs.read (cbuffer, sizeof(cbuffer));
cout << "rdstate() = 0x" << hex << fs.rdstate() << dec << "; gcount() = "
<< fs.gcount() << endl;
}
cout << "rdstate() = 0x" << hex << fs.rdstate() << dec << endl;
}
int main ()
{
foo ();
return 0;
}

http://groups.google.com/group/test-av/msg/0c4d3da487594ab7
Output for g++ (Cygwin)

It seems that behavior of g++ is wrong here.
Output for gpp (Djgpp)
---
rdstate() = 0x0; gcount() = 1500
rdstate() = 0x0; gcount() = 1500
rdstate() = 0x0; gcount() = 1500
rdstate() = 0x0; gcount() = 1500
rdstate() = 0x0; gcount() = 1500
rdstate() = 0x6; gcount() = 1071
rdstate() = 0x6
---
Output for Microsoft C++
---
rdstate() = 0x0; gcount() = 1500
rdstate() = 0x0; gcount() = 1500
rdstate() = 0x0; gcount() = 1500
rdstate() = 0x0; gcount() = 1500
rdstate() = 0x0; gcount() = 1500
rdstate() = 0x3; gcount() = 1071
rdstate() = 0x3

Parent catchs SIGINT via sigINT_handler1,
but Child doesn't catch SIGINT via sigINT_handler2.
How can Child catch SIGINT with its own signal handler?

The problem is not only with VC++ RTL.
The program has been compiled:
* with Microsoft C++ 13.00.9466 for 80x86
cl /EHsc program.cpp -o a_ms.exe
* with gcc version 3.3.1 (cygming special)
g++ -mno-cygwin -o a_mgw program.cpp // Use the Mingw32 interface
g++ -o a_cyg program.cpp // Cygwin
Here are results:
$ a_ms
[---omitted---]
Difference in wall clock is 11
Difference in CPU ticks is 11.847
$ a_mgw
[---omitted---]
Difference in wall clock is 10
Difference in CPU ticks is 10.925
$ a_cyg
[---omitted---]
Difference in wall clock is 9
Difference in CPU ticks is 0.03
Here are DLLs:
a_ms.exe
C:\WINNT\system32\KERNEL32.dll
C:\WINNT\system32\NTDLL.DLL
a_mgw.exe
C:\WINNT\system32\msvcrt.dll
C:\WINNT\system32\KERNEL32.dll
C:\WINNT\system32\NTDLL.DLL
a_cyg.exe
C:\cygwin\bin\cygwin1.dll
C:\WINNT\system32\ADVAPI32.DLL
C:\WINNT\system32\NTDLL.DLL
C:\WINNT\system32\KERNEL32.DLL
C:\WINNT\system32\RPCRT4.DLL
It seems that the problem is in DLLs (?).

Is there any special mailing-list/newsgroup to discuss gcc-java?

pthreads, printf and cout
Hi,
Behavior of printf and cout in a program below is different : cout prints nothing.
What is wrong?
===
Windows 2000 Professional
CYGWIN_NT-5.0 1.5.4(0.94/3/2)
gcc version 3.3.1 (cygming special)

printf ("printf : Run Start\n");
cout << "cout : Run Start" << endl;
sleep (3);
printf ("printf : Run Finish\n");
cout << "cout : Run Finish" << endl;
}
int main ()
{
pthread_t t1;
pthread_create(&t1, NULL, Run, NULL);
int errNum = pthread_join(t1, NULL);
printf ("printf : errNum = %d\n", errNum);
cout << "cout : errNum = " << errNum << endl;
}

printf : errNum = 0
// cout prints nothing

Printable information in executables
Executable files contain various printable information. For instance, list of used DLLs. However those files contain neither compiler name nor compiler version. It seems to be worth including something like "gcc version 3.3.1 (cygming special)" in executables. Next question. Is it possible to add 'user related printable information' to executables (through compilation option or something else)? -- ===== Alex Vinokur mailto:[EMAIL PROTECTED] http://mathforum.org/library/view/10978.html news://news.gmane.org/gmane.comp.lang.c++.perfometer = -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
