Google Logging (glog) macros

Warning

Pigweed strongly recommends sticking to printf-style logging instead of C++ stream-style glog logging unless absolutely necessary. These macros are only provided for compatibility with non-embedded code.

Macros
#define	LOG(glog_level)
#define	LOG_IF(glog_level, expr)

Macro Definition Documentation

LOG

#define LOG

(

glog_level

)

Value:

  _PW_LOG_GLOG(_PW_LOG_GLOG_DECLARATION_##glog_level, \
               PW_CONCAT(GlogStreamingLog, __COUNTER__))

A subset of the streaming Google logging (glog) macros are supported:

• LOG(glog_level)
• LOG_IF(glog_level, condition)

The supported glog levels are DEBUG, INFO, WARNING, ERROR, FATAL, and DFATAL

This means the following are NOT supported:

• glog level DFATAL
• {D,P,SYS}LOG*
• {,D}VLOG*
• {,D}CHECK*
• LOG_EVERY_*, LOG_IF_EVERY_*, LOG_FIRST_N

LOG_IF

#define LOG_IF	(		glog_level,
			expr
	)

Value:

  _PW_LOG_GLOG_IF(_PW_LOG_GLOG_DECLARATION_##glog_level, \
                  expr,                                  \
                  PW_CONCAT(GlogStreamingLog, __COUNTER__))

PW_LOG_CFG_GLOG_BUFFER_SIZE_BYTES

#define PW_LOG_CFG_GLOG_BUFFER_SIZE_BYTES   128

The size of the stack-allocated buffer used by the Google Logging (glog) macros. This only affects the glog macros provided through pw_log/glog.h.

Undersizing this buffer will result in truncated log messages.
