NAME
       index, rindex, strchr, strrchr - Search for character in string

LIBRARY
       Standard C Library (libc.so, libc.a)

SYNOPSIS
       #include <strings.h>

       char *index(
	       const char *s,
	       int c);

       char *rindex(
	       const char *s,
	       int c);

       #include <string.h>

       char *strchr(
	       const char *s,
	       int c);

       char *strrchr(
	       const char *s,
	       int c);

STANDARDS
       Interfaces documented on this reference page conform to industry standards as follows:

       index(), rindex():  XPG4-UNIX

       strchr(), strrchr():  XPG4, XPG4-UNIX

       Refer to the standards(5) reference page for more information about industry standards and associated tags.

PARAMETERS
       Specifies the string to search.	Specifies a character, expressed as an int data type, to search for.

DESCRIPTION
       The  index()  function locates the first occurrence of the integer specified by the c parameter, which is converted to an unsigned char, in
       the string pointed to by the s parameter.  The terminating null byte is treated as part of the string pointed to by the s parameter.

       The rindex() function locates the last occurrence of the integer specified by the c parameter, which is converted to a char value,  in  the
       string pointed to by the s parameter.  The terminating null byte is treated as a part of the string pointed to by the s parameter.

       The strchr() and strrchr() functions provide the same functionality as the index() and rindex() functions, respectively.

       If c is a null byte ('') in any of these functions, the function locates the terminating null byte of s.

RETURN VALUES
       Upon  successful  completion, these functions return a pointer to the byte in the scanned string. When the byte specified by parameter c is
       not found, a null pointer is returned.
