I'm testing this in a function but it doesn't work:
FD_t fd;
int rc;
fd = Fopen(headerFile, O_RDONLY);
if (Fileno(fd) < 0) {
return 1;
}
rc = rpmReadPackageFile(ts, fd, headerFile, h);
Fopen() returns always 0 for fd. I've tried with different existing full paths
or rpm and src.rpm files. E.g. my application prints:
Warning: reading
/var/ftp/pub/openmamba/devel/SRPMS.base/54321-1.0.2001.11.16-3mamba.src.rpm
Warning: 54321-1.0.2001.11.16-3mamba.src.rpm: unable to read header (No such
file or directory); skipping.
headerFile in Fopen is the path shown and "No such file or directory" is the
string conversion of errno.
Currently I don't have a lot of ideas about what is wrong with this code, am I
using Fopen and rpmReadPackageFile correctly or do I have to change approach
here as well?
Thanks.
