    • A method for creating a specific POSIX style locale source file, on demand, suitable for compilation in a computer is provided the method comprising, receiving a request submitted for the specific POSIX style locale, and obtaining a plurality of localization values related to the specific POSIX style locale. Next, determining a category within the plurality of localization values and selecting process routines dependent upon the category, and then selectively extracting the category information. After extracting the category information is stored into a memory of the computer. A determination is made regarding more categories to process, which might result in processing the remaining categories, otherwise assembling the extracted information into the POSIX style locale source file. Assembling may entail addition of no files or files such as LC-CTYPE and LC_COLLATE to form a locale source suitable for compilation.
    • 提供了一种用于根据需要创建适于在计算机中编译的特定POSIX样式语言环境源文件的方法,所述方法包括:接收针对所述特定POSIX样式语言环境提交的请求,以及获得与所述特定POSIX相关的多个定位值 样式地区。 接下来,确定多个定位值内的类别,并根据该类别选择处理例程,然后选择性地提取类别信息。 提取后的类别信息存储到计算机的内存中。 确定要处理的更多类别,这可能导致处理其余类别,否则将提取的信息组装到POSIX样式区域设置源文件中。 组装可能需要添加没有文件或文件,如LC-CTYPE和LC_COLLATE来形成适合编译的区域设置源。
