この記事では、C言語における return 1 という表現の基本的な意味について解説します。. また、 return 1 以外の選択肢や他の値やステートメントの利用例についても紹介します。 C言語のプログラミング初心者の方でも理解しやすいように、具体的なコード例を交えて説明します。 This is not valid syntax. Try something like: struct MyStruct s = {1,2,3}; return s; But it would be better to show how exactly MyStruct is declared, just in case. No, the OP isn't casting anything but returning a compound literal. But this is a C99 feature which apparently isn't ubiquitous. On systems that use libc, which is pretty much the majority of Unix systems, the following things happens when a program exits:.
