编译c 代码时 dpc_new 工具新增参数 CHAR_MAP=STRING。这样会转为 string 处理就可以避免这个问题了。ODBC 应用程序执行 SQLConnect 函数时报错 【问题描述】ODBC 应用程序执行 SQLConnect 函数时报错:“SQL_INVALID_HANDLE = -2 checkError function was called with an invalid handle!!”。
问处理共享内存时的C分段故障EN共享内存是进程间通信中最简单的方式之一。共享内存允许两个或更多进程访问同一块内存，就如同 malloc() 函数向不同进程返回了指向同一个物理内存区域的指针。当一个进程改变了这块地址中的内容的时候，其它进程都会察觉到这个更改。

如果学习过编译原理则不难理解,一般高级语言程序编译的过程莫过于:预处理、编译、汇编、链接。gcc在后台实际上也经历了这几个过程,我们可以通过-v参数查看它的编译细节,如果想看某个具体的编译过程,则可以分别使用-E,-S,-c和 -O,对应的后台工具则分别为cpp,cc1,as,ld。下面我们将逐步分析这几个过程以及相关...
