stream_buffer.h

size_t xStreamBufferSpacesAvailable( StreamBufferHandle_t xStreamBuffer );

Stream buffer functionality is enabled by including the FreeRTOS/source/stream_buffer.c source file in the build.

Parameters:
xStreamBuffer   The handle of the stream buffer being queried.
Returns:
The number of bytes that can be written to the stream buffer before the stream buffer would be full.
