+Subject: [PATCH 2/2] cmocka: feature to forwarding cmocka log message to
+ custom channel
+
+Add custom log message implementation to support different backend output, such as linux (vsyslog):
+
+https://www.gnu.org/software/libc/manual/html_node/syslog_003b-vsyslog.html
+
+redefine the vprint output function to native implement:
+
+1. Enable platfrom include: -DCMOCKA_PLATFORM_INCLUDE
+2. Add cmocka platform header to forwarding the log message to custom channel
+
+cmocka_platform.h:
+
+| #ifndef CMOCKA_PLATFORM_H_
+| #define CMOCKA_PLATFORM_H_
+|
+| #include <syslog.h>
+|
+| #define cmocka_vprint_message(f,a) vsyslog(LOG_INFO,f,a)
+| #define cmocka_vprint_error(f,a) vsyslog(LOG_ERR,f,a)
+|
+| #endif /* CMOCKA_PLATFORM_H_ */
