Hi,
I am now using ReadFile in a loop to read stdin, It works fine for small amounts of
data but when the data piped is large, it crashes saying "The Process tried to write
to a nonexistent pipe" ( For Eg dir /s|prog.exe on the C drive at cmd)
Any idea how I can get past this?
Ignorant question : Can I use anonymous pipe concept here to read in from the pipe. Or
that is used only with user created pipes?
I am doing something like this :
if(GetFileType(h) == FILE_TYPE_PIPE)
{
while(1)
{
buf = new char[length];
bResult = ReadFile(h, buf, length, NULL);
buf[bytesRead] = '\0';
if(bResult & bytesRead == 0 ) break; //EOF
buf = 0;
bytesRead = 0;
}
}
ReadFile throws an error sometimes, and sometimes it works fine. I think I am
missing something here, if somebody has any idea, please mail back.
Thanks and Regards,
Dolly
