REG_NOTEOL:'$' 不被匹配,除非regcomp()的cflags参数指定REG_NEWLINE;输出:匹配正常则返回0;否则返回错误信息(非0)。regerror():输出错误信息; regfree():释放正则表达式。示例分析#include <stdint.h> #include <stdio.h> #include <stdlib.h> #include <regex.h> #define ARRAY_SIZE(arr) (sizeof((...

search("dog", 1) # No match; search doesn't include the "d" Pattern.match(string[, pos[, endpos]]) 如果string 的开始位置 能够找到这个正则样式的任意个匹配,就返回一个相应的 匹配对象。如果不匹配,就返回 None ;注意它与零长度匹配是不同的。 可选参数 pos 和endpos 与search() 含义相同。
