uchar * cPatPmtGenerator::GetPat | ( | void | ) |
Returns a pointer to the PAT section, which consists of exactly one TS packet.

References IncCounter(), pat, and patCounter.
uchar * cPatPmtGenerator::GetPmt | ( | int & | Index | ) |
Returns a pointer to the Index'th TS packet of the PMT section.
Index must be initialized to 0 and will be incremented by each call to GetPmt(). Returns NULL is all packets of the PMT section have been fetched..

void cPatPmtGenerator::SetVersions | ( | int | PatVersion, |
int | PmtVersion ) |
Sets the version numbers for the generated PAT and PMT, in case this generator is used to, e.g., continue a previously interrupted recording (in which case the numbers given should be derived from the PAT/PMT versions last used in the existing recording, incremented by 1.
If the given numbers exceed the allowed range of 0..31, the higher bits will automatically be cleared. SetVersions() needs to be called before SetChannel() in order to have an effect from the very start.
