PortAudio  2.0
Files
Source code common to all implementations

Files

file  pa_allocation.c
 

Allocation Group implementation.


file  pa_allocation.h
 

Allocation Group prototypes. An Allocation Group makes it easy to allocate multiple blocks of memory and free them all at once.


file  pa_converters.c
 

Conversion function implementations.


file  pa_converters.h
 

Conversion functions used to convert buffers of samples from one format to another.


file  pa_cpuload.c
 

Functions to assist in measuring the CPU utilization of a callback stream. Used to implement the Pa_GetStreamCpuLoad() function.


file  pa_cpuload.h
 

Functions to assist in measuring the CPU utilization of a callback stream. Used to implement the Pa_GetStreamCpuLoad() function.


file  pa_debugprint.c
 

Implements log function.


file  pa_debugprint.h
file  pa_dither.c
 

Functions for generating dither noise.


file  pa_dither.h
 

Functions for generating dither noise.


file  pa_endianness.h
 

Configure endianness symbols for the target processor.


file  pa_front.c
 

Implements PortAudio API functions defined in portaudio.h, checks some errors, delegates platform-specific behavior to host API implementations.


file  pa_hostapi.h
 

Interfaces and representation structures used by pa_front.c to manage and communicate with host API implementations.


file  pa_memorybarrier.h
file  pa_process.c
 

Buffer Processor implementation.


file  pa_process.h
 

Buffer Processor prototypes. A Buffer Processor performs buffer length adaption, coordinates sample format conversion, and interleaves/deinterleaves channels.


file  pa_ringbuffer.c
file  pa_ringbuffer.h
 

Single-reader single-writer lock-free ring buffer.


file  pa_stream.c
 

Stream interfaces, representation structures and helper functions used to interface between pa_front.c host API implementations.


file  pa_stream.h
 

Stream interfaces, representation structures and helper functions used to interface between pa_front.c host API implementations.


file  pa_trace.c
 

Real-time safe event trace logging facility for debugging.


file  pa_trace.h
 

Real-time safe event trace logging facility for debugging.


file  pa_types.h
 

Definition of 16 and 32 bit integer types (PaInt16, PaInt32 etc)


file  pa_util.h
 

Prototypes for utility functions used by PortAudio implementations.


file  pa_hostapi_skeleton.c
 

Skeleton implementation of support for a host API.
