Meanings of symbols in the C ++ library file:

All symbols start with an underscore (_ z) and an uppercase letter (_ z). For symbols in a class or namespace, they are followed by "N ", the name of each namespace and class is followed by the length of the name string before each name, followed by an uppercase letter "E". For a function, its parameter list is after E, for example, the float type is the letter "F". For example, for the function n: C: func (INT, float ), the symbol in the library or target file is _ zn1n1c4funceif. The binutils tool C ++ filt can directly translate the symbol into the name in the Code, for example, the command C ++ filt zn1n1c4funceif, and the output result is N: C :: func (INT, float)
