General enough?Of course there are all sorts of issues about /how/ the items in thestruct(s) should be printed. Generally speaking, I''d write thestruct-printer function as part of the cluster of functions thatbelong with the struct [1]; since large structs from smaller structsgrow, I wouldn''t be faced with the "oh /frelling/ tedium, I haveto write a print function for a 117-element struct /now/!". (AlsoI wouldn''t write a flat 117-element struct anyway.)[1] EG print one, initialise one, malloc one, free (a pointer to) one,test two of them for equality/similarity, construct one from asimple string description, send one to bed with a cup of cocoaand a good book.--Chris "this week''s vote: /The Riddle-Master of Hed/" Dollin"It took a very long time, much longer than the most generous estimates."- James White, /Sector General/ ka*****@gmail.com wrote:I have to print several large structs to print the screen.I was wondering if thers a tool to do so automaticlyYou may like to look at some platform-specifics (like the STABS andDWARF debugging formats) to see if they are appropriate, but that''s notpart of the standard C language.For general purposes, Chris Dollin''s suggestion seems most appropriate. 这篇关于自动打印struct的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
