00015 //Symbian wrappers around tremor(Fixedpoint decoder library) and libvorbis(Floatpoint encoder) are shared between OggPlayController
00016 //and the OggRecordController. The external APIs to these two libraries differ in only few places and hence SYMBIAN_CODEC_FLOAT_POINT 
00017 //is used whereever we need to differentiate.

00020 // OggVorbis C libraries are not alloc safe. So we create a separate heap for C library calls with enough space well before 
00021 // the codec starts processing and we switch to the new heap before making calls to the methods in these libraries. 
00022 // Chunk and Heap sizes are taken such a way that we have enough space on the new heap to avoid OOM situations to the 
00023 // maximum extent possible. Also the malloc, calloc and realloc functions in the C libraries are modified to leave with KErrMemory 
00024 // when the allocation fails. We TRAP the error and cleanup the new heap we had created. This way the library calls are made alloc safe.
00025 // SYMBIAN_SEP_HEAP is provided to enable/disable this separate heap mechanism.
