DESCRIPTION

       Ns_Match(a, b)

              Compare the beginnings of two strings, case insensitively.  The comparison stops when the  end  of
              the shorter string is reached.  Return NULL if no match, b if match.

       Ns_NextWord(line)

              Return  a  pointer  to  first character of the next word in a string; words are separated by white
              space.  The returned pointer points into the original string.  For example, Ns_NextWord("abc def")
              returns a pointer to the 'd' in that string.

       Ns_StrCaseFind(s1, s2)

              Locate the first occurrence of substring s2 within string s1 in  a  case-insensitive  manner.  The
              terminating  ' '  characters  are  not  compared.  Returns  a  pointer  that points into s1.  Uses
              strstr(3) to do its work.

       Ns_StrCopy(str)
              ns_strcopy(str)

              Copy a string or NULL value  using  Ns_Malloc.   The  Ns_StrCopy  function  is  identical  to  the
              Ns_StrDup  function  but allows for the string parameter to be NULL, in which case Ns_StrCopy does
              nothing and returns NULL.

       Ns_StrDup(str)
              ns_strdup(str)

              Copy a string using Ns_Malloc. The Ns_StrDup function calls Ns_Malloc to allocate enough memory to
              make a copy of the given string.

       Ns_StrNStr(pattern, expression)

              Search through pattern for expression, case insensitively. Return a pointer that points  to  where
              the match begins within pattern, or NULL if expression is not contained in pattern.

       Ns_StrToLower(string)

              Convert string to lowercase. Returns pointer to original string. Original string will be modified.

       Ns_StrToUpper(string)

              Convert string to uppercase. Returns pointer to original string. Original string will be modified.

       Ns_StrTrim(string)

              Trim  leading  and  trailing  white  space  from  string.  A pointer to the trimmed string will be
              returned, which will be in the original string. Do not lose your original pointer to the string if
              you later need to free it.

       Ns_StrTrimLeft(string)

              Trim leading white space from string. A pointer to the trimmed string will be returned, which will
              be in the original string. Do not lose your original pointer to the string if you  later  need  to
              free it.

       Ns_StrTrimRight(string)

              Trim  trailing  white  space  from  string.  The original string pointer will be returned, but the
              string will have been modified: a ' 's will have been placed right after the  last  non-whitespace
              character of the string.

       Ns_StringPrint(string)

              Print a string to stdout.
