Rexx scripts invoke external functions in the same manner as built - in or user - written functions once access is established to the external function library Rexx脚本像调用内置函数或用户编写的函数一样调用外部函数（假设已建立到外部函数库的连接） 。
Also , perl is very good at linking to c c code and libraries , and the built - in perl functions such as sort and print are usually nearly as fast as the c code for the same thing 此外， perl能很方便地与c / c + +代码或库连接，且某些perl内置函数并不比c代码慢，如排序或打印等。
Built - in functions display snapshot statistics about sql server activity since the server was started ; these statistics are stored in predefined sql server counters 内置函数可显示自启动服务器以来有关sql server活动的快照统计信息，这些统计信息存储在预定义的sql server计数器中。
Shows the implementation of five transact - sql string functions that provide the same string modify functions as built - in ones , but with additional supplementary character - aware capability to handle both unicode and supplementary character strings 显示五个transact - sql字符串函数的实现，这些函数提供了与内置函数相同的字符串修改功能，不同的是增加了识别增补字符的功能，因此既可以处理unicode字符串，也可以处理由增补字符组成的字符串。
This sample shows the implementation of five transact - sql string functions that provide the same string manipulation functions as built - in ones , but with additional supplementary character - aware capability to handle both unicode and supplementary character strings 此示例显示了五个transact - sql字符串函数的实现方式。这些函数提供的字符串操作功能与内置函数相同，但增加了补充字符识别功能，因此既能处理unicode字符串，又能处理补充字符串。
