In this code has a color that is what mean? Functions are defined how can so???

CodePudding user response:

Generally is a macro, the different compiler might be different

CodePudding user response:

@ akirya C language function definition before how can have macro prefix ah,,, didn't understand...

CodePudding user response:

refer to the second floor jions7ihj response:

@ akirya C language function definitions before how can have macro prefix ah,,, didn't understand...

This is an optional thing, to the compiler,
With C language do not have what relation,

CodePudding user response:

# define JEMALLOC_INLINE inline
Estimated that where there is such a macro definition
