p_err

Pointer to variable that will receive the return error code from this function:

NET_IPv4_ERR_NONE

Notes / Warnings

This function should only be called by appropriate network application function(s) [e.g., DHCP initialization functions]. However, if the application attempts to dynamically configure IPv4 address(es), it must call NetIPv4_CfgAddrAddDynamicStart() before calling NetIPv4_CfgAddrAddDynamic.
