1、近來(lái)又有人在群里問(wèn)如何用c語(yǔ)言編制dll文件（動(dòng)態(tài)鏈接庫(kù)）。原來(lái)沒(méi)有對(duì)這個(gè)問(wèn)題太在意過(guò)，也沒(méi)有嘗試過(guò)任何解決方案，畢竟原來(lái)我是用vb的（現(xiàn)在用.net），做個(gè)dll只不過(guò)是點(diǎn)選一下建立activeX?dll工程的圖標(biāo)而已。今天在網(wǎng)上與朋友聊天，看了他指給我的幾個(gè)幾個(gè)文件，用MingW將C程序編譯成dll文件的例子，我恍然大悟，原來(lái)講C程序編譯成dll文件只不過(guò)是在要公開(kāi)的接口函數(shù)聲明前面加上幾個(gè)特定的修飾符而已。于是用dev-cpp建了個(gè)dll的默認(rèn)文檔，一切都很明了。（我把源代碼貼在下面）/*dll.h文件*/
