How to view the definition of a struct under Linux

These two days in the learning socket, writing code, the old will forget a struct member, I generally used to grep solve. The symbol definitions under Linux are basically in the /usr/include folder, so I usually use the following commands:

 
   
  

  
    
   
grep -r ‘struct addrinfo‘ /usr/include/*.h
