NAME

       strstr - Finds a substring

LIBRARY

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

SYNOPSIS

       #include <string.h>

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

STANDARDS

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

       strstr():  ISO C, XPG4, XPG4-UNIX

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

PARAMETERS

       Specifies the character string being searched.  Specifies the substring to be located.

DESCRIPTION

       The  strstr()  function	locates  the  first occurrence in the string pointed to by the s1 parameter of the sequence of bytes in the string
       pointed to by the s2 parameter, excluding the terminating null character.

RETURN VALUES

       On successful completion, the strstr() function returns a pointer to the located string or a null pointer if the string is not found.  When
       the s2 parameter points to a string having 0 (zero) length, the strstr() function returns the string pointed to by parameter s1.

NAME

       wcsstr - Finds a wide-character substring

LIBRARY

       Standard C Library (libc)

SYNOPSIS

       #include <wchar.h>

       wchar_t *wcsstr(      const wchar_t *s1,      const wchar_t *s2);

STANDARDS

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

       wcsstr(): XSH5.0

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

PARAMETERS

       Specifies the wide-character string being searched.  Specifies the wide-character substring to be located.

DESCRIPTION

       The  wcsstr()  function	locates  the  first occurrence in the wide-character string pointed to by the s1 parameter of the sequence of wide
       characters in the wide-character string pointed to by the s2 parameter, excluding the terminating null wide character.

RETURN VALUES

       Upon successful completion, the wcsstr() function returns a pointer to the located wide-character substring or a null pointer when the sub-
       string  is  not	found.	If the s2 parameter points to a wide-character substring having 0 (zero) length, the wcsstr() function returns the
       entire wide-character string pointed to by parameter s1.

       [Tru64 UNIX]  On error, the function returns a null pointer.
