[Rpm-maint] Logging rpm installation logs to file

[viren.sharma at tcs.com]

Hi Panu,

I've tried redirecting output using rpmtsSetScriptFd()but it is not 
working.

I've done something like this:
****************************************
>     FILE *fdLogFile;
>     fdLogFile = fopen("LogFile.txt", "w");
>     if (fdLogFile == NULL)
>     {
>         printf("Unable to open file LogFile.txt");
>         return RPM_FAILURE;
>     }
> 
..
..
> rpmtsSetScriptFd(ts, (FD_t)&fdLogFile);
..
..
>     fclose(fdLogFile);

****************************************

On running this I am getting the following error:

testRpm: ./rpmio_internal.h:525: c2f: Assertion `fd && fd->magic == 
0x04463138' failed.
Aborted

Please help me out.

You can redirect the scriptlet execution output to arbitrary file with 
rpmtsSetScriptFd().
