STRSTR(3)		  OpenBSD Programmer's Manual		     STRSTR(3)

NAME
     strstr, strcasestr - locate a substring in a string

SYNOPSIS
     #include <string.h>

     char *
     strstr(const char *big, const char *little);

     char *
     strcasestr(const char *big, const char *little);

DESCRIPTION
     The strstr() function locates the first occurrence of the NUL-terminated
     string little in the NUL-terminated string big.

     The strcasestr() function is similar to strstr() but ignores the case of
     both strings.

     If little is an empty string, big is returned; if little occurs nowhere
     in big, NULL is returned; otherwise a pointer to the first character of
     the first occurrence of little is returned.

SEE ALSO
     memchr(3), strchr(3), strcspn(3), strpbrk(3), strrchr(3), strsep(3),
     strspn(3), strtok(3)

STANDARDS
     The strstr() function conforms to ANSI X3.159-1989 (``ANSI C'').

HISTORY
     The strcasestr() function first appeared in OpenBSD 3.8.
