DESCRIPTION
       These functions perform various operations on strings (arrays of  char‐
       acters),  which  are  given  as  arguments  s, s1, and s2 that point to
       strings. Depending on the function, strings may be either terminated by
       a null character or consist of a length of n bytes. They  are  designed
       for  use  with  encodings representing each character as a single byte,
       and all character counts are measured in individual bytes,  even  if  a
       string  with  multibyte  characters is used. They do not check for null
       pointers, and programs may crash if passing null or  otherwise  invalid
       pointers to these functions, or specifying sizes larger than the memory
       allocation  in  use for the string. Use of adi(7) may help in detecting
       out-of-bounds access or invalid pointer usage in code.

   strchr(), strrchr(), strchrnul()
       The strchr() function returns a pointer to the first  occurrence  of  c
       (converted  to a char) in string s, or a null pointer if c does not oc‐
       cur in the string.


       The strrchr() function returns a pointer to the last  occurrence  of  c
       (converted  to a char) in string s, or a null pointer if c does not oc‐
       cur in the string.


       The null character terminating a string is considered to be part of the
       string, and a pointer to it will be returned if c is 0.


       The strchrnul() function is similar to strchr() except that if c is not
       found in s, it returns a pointer to the null byte  at  the  end  of  s,
       rather than NULL.


       These functions only work with single byte characters.

   strcspn(), strspn()
       The  strcspn()  function  returns  the length of the initial segment of
       string s1 that consists entirely of bytes not from string s2. The  str‐
       spn()  function  returns the length of the initial segment of string s1
       that consists entirely of bytes from string s2.

   strpbrk()
       The strpbrk() function returns a pointer to  the  first  occurrence  in
       string s1 of any byte from string s2, or a null pointer if no byte from
       s2 exists in s1.

   strstr(), strnstr(), strcasestr()
       The  strstr()  function  locates  the first occurrence of the string s2
       (excluding the terminating null character) in string s1 and  returns  a
       pointer  to  the located string, or a null pointer if the string is not
       found. If s2 points to a string with zero length (that is,  the  string
       ""), the function returns s1.


       The  strnstr() function locates the first occurrence of the null-termi‐
       nated string s2 in the string s1, where  not  more  than  n  bytes  are
       searched.  Characters  that  appear  after  a  '\0'  character  are not
       searched.


       The strcasestr() function is similar to strstr(), but  ignores  differ‐
       ences  in case when comparing lowercase and uppercase characters, using
       the current locale of the process to determine the case of the  charac‐
       ters.

HISTORY
       The strcasestr(), strchrnul(), and strnstr() functions  were  added  to
       Oracle Solaris in the Solaris 11.0.0 release.


       The  strchr(),  strcspn(), strpbrk(), strrchr(), strspn(), and strstr()
       functions have been included in all Sun and Oracle releases of Solaris.
