NAME

       strpbrk - Find one of a set of bytes in a string

LIBRARY

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

SYNOPSIS

       #include <string.h>

       char *strpbrk(
	       const char *s1,
	       const char *s2);

STANDARDS

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

       strpbrk():  XPG4, XPG4-UNIX

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

PARAMETERS

       Specifies a string being searched.  Specifies a set of bytes in a string.

DESCRIPTION

       The strpbrk() function scans the string pointed to by the s1 parameter for the first occurrence of any byte in the string pointed to by the
       s2 parameter.  The strpbrk() function treats the s2 parameter as a series of bytes and does not search for multibyte characters. The  wcsp-
       brk() function provides the same functionality but searches for characters rather than bytes.

RETURN VALUES

       Upon  successful  completion, the strpbrk() function returns a pointer to the matched byte. When no byte in the string pointed to by the s2
       parameter occurs in the string pointed to by the s1 parameter, a null pointer is returned.

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.
