【C语言】va_list(可变参数处理) C 语言中的 va_list 类型允许函数接受可变数量的参数,这在编写需要处理不定数量参数的函数时非常有用。va_list 类型是在 stdarg.h 头文件中定义的,它允许函数处理可变数量的参数。下面我们将详细介绍 va_list 的用法以及实际应用示例。 一、va_list的用法 va_list 是一个指向...

no%macro 不执行 -Ncheck 的任何 macro 检查。 no%extern 不执行 -Ncheck 的任何 extern 检查。 缺省值为 -Ncheck=%none。指定 -Ncheck 与指定 -Ncheck=%all 等效。 多个值可以用逗号分隔,例如 -Ncheck=extern,macro。 示例: % lint -Ncheck=%all,no%macro 执行除宏检查之外的所有检查。 4.3.2...

Beware of the va_ prefix found in stdarg.h or varargs.h. Use a digit or a non-capital letter somewhere within the first few characters of all macro names. Almost all names beginning with an E are reserved if errno.h is #included. ...
Historic (i.e. K&R) variadic argument processing is declared in <varargs.h> but should not be used as it’s obsolete. Standard variadic argument processing (the one described here and declared in <stdarg.h>) was introduced in C89; the va_copy macro was introduced in C99 but provided by...
