参数：

类型参数名称
const char *str
825  cp等于str
828  如果cp不等于'|'则返回
830  cp自加
831  当Note: isspace() must return false for %NUL-terminator ( * cp)循环
832  cp自加
833  如果非str_has_prefix - Test if a string has a given prefix*@str: The string to test*@prefix: The string to see if @str starts with* A common way to test a prefix of a string is to do:* strncmp(str, prefix, sizeof(prefix) - 1)* But this can lead to bugs due to 则
834  kdb_printf("invalid 'pipe', see grephelp\n")
835  返回
837  cp加等于5
838  当Note: isspace() must return false for %NUL-terminator ( * cp)循环
839  cp自加
840  cp2等于strchr - Find the first occurrence of the character c in the string s.*@s: the string to be searched*@c: the character to search for
841  如果cp2则cp2等于'\0'
843  len等于strlen - Find the length of a string*@s: The string to be sized
844  如果len恒等于0则
845  kdb_printf("invalid 'pipe', see grephelp\n")

854  如果非cp2则
855  kdb_printf("invalid quoted string, see grephelp\n")
856  返回
858  cp2等于'\0'
860  kdb_grep_leading等于0
861  如果cp恒等于'^'则

865  len等于strlen - Find the length of a string*@s: The string to be sized
866  kdb_grep_trailing等于0
867  如果*cp加len减1的差恒等于'$'则
868  kdb_grep_trailing等于1
869  *cp加len减1的差等于'\0'
871  len等于strlen - Find the length of a string*@s: The string to be sized
872  如果非len则返回
874  如果len大于等于KDB_GREP_STRLEN则
