| * debug_flags dynamically controls what LWIP_DEBUGF() prints. |
| * |
| * LWIP_DEBUGF(debug, message) prints if (debug & debug_flags) is true |
| * because: |
| * lwipopts.h defines LWIP_DBG_TYPES_ON as debug_flags |
| * lwip/debug.h defines LWIP_DEBUGF() to test (debug & LWIP_DBG_TYPS) |
| * |
| * You should also check lwipopts.h to understand how 'debug's are defined. |
| * |
| * You can enable/disable the debug messages with these flags: |
| * |
| * LWIP_DBG_ON - enables all debug messages |
| * LWIP_DBG_OFF - disables all debug messages |
| * |
| * You can also selectively enable the debug messages by types: |
| * |
| * LWIP_DBG_TRACE - enables if debug includes LWP_DBG_TRACE |
| * LWIP_DBG_STATE - enables if debug includes LWP_DBG_STATE |
| * LWIP_DBG_FRESH - enables if debug includes LWP_DBG_FRESH |
