FreeRTOS+TCP is still in the lab
FreeRTOS+TCP is already used in commercial products and we encourage you to try it yourself. Be aware however that we are still refining its design, and the source code and documentation do not yet meet Real Time Engineers Ltd's strict quality standards.
Please use the forum for support, feedback and ideas, or contact us directly if you have a specific business interest.

vReleaseNetworkBuffer()
[Ethernet Driver Porting API]

FreeRTOS_IP_Private.h
NetworkBufferManagement.h
void vReleaseNetworkBuffer( uint8_t *pucPayloadBuffer );
		

Returns to the TCP/IP stack an Ethernet buffer that was previously obtained from the TCP/IP stack.

vReleaseNetworkBuffer() would normally only be used by a zero copy driver to release buffers that were previously allocated to DMA descriptors. Normally network buffers are allocated and released along with descriptors using pxGetNetworkBufferWithDescriptor() and vReleaseNetworkBufferAndDescriptor() respectively.

vReleaseNetworkBuffer() must not be called from an interrupt service routine (ISR).


Parameters:

pucPayloadBuffer   A pointer to the Ethernet buffer being released (returned to the TCP/IP stack).


Example usage:

Examples are provided on the Porting FreeRTOS to a Different Microcontroller page.
