用于转义字符串的标准c库 [英] standard c library for escaping a string

问题描述

例如，如果我有C字符串：

  char example [] =first line\\\
second line：\inner quotes\; 
  

我想打印

 first line\\\
second line：\inner quotes\
  

有没有一个库函数可以为我做这个转换？滚动我自己只是看起来有点愚蠢。

奖金积分，如果我可以给它一个长度逃脱（所以它停止之前或之后的

解决方案

如果您正在编写GPL内容，可以使用 http：// git。 savannah.gnu.org/gitweb/?p=gnulib.git;a=blob;f=lib/quotearg.c;hb=HEAD

Is there a standard C library function to escape C-strings?

For example, if I had the C string:

char example[] = "first line\nsecond line: \"inner quotes\"";

And I wanted to print

"first line\nsecond line: \"inner quotes\""

Is there a library function that will do that transformation for me? Rolling my own just seems a little silly.

Bonus points if I can give it a length to escape (so it stops before or beyond the \0).

解决方案

If you were writing GPL stuff you might use http://git.savannah.gnu.org/gitweb/?p=gnulib.git;a=blob;f=lib/quotearg.c;hb=HEAD
