       string operations

SYNOPSIS
       #include <strings.h>

       int strcasecmp(const char *s1, const char *s2);
	      Compare the strings s1 and s2 ignoring case.

       int strncasecmp(const char *s1, const char *s2, size_t n);
	      Compare the first n characters of the strings s1 and s2 ignoring
	      case.

       char *index(const char *s, int c);
	      Return  a	 pointer to the first occurrence of the character c in
	      the string s.

       char *rindex(const char *s, int c);
	      Return a pointer to the last occurrence of the  character	 c  in
	      the string s.

       #include <string.h>

       char *stpcpy(char *dest, const char *src);
	      Copy  a  string from src to dest, returning a pointer to the end
	      of the resulting string at dest.

       char *strcat(char *dest, const char *src);
	      Append the string src to the string dest,	 returning  a  pointer
	      dest.

       char *strchr(const char *s, int c);
	      Return  a	 pointer to the first occurrence of the character c in
	      the string s.

       int strcmp(const char *s1, const char *s2);
	      Compare the strings s1 with s2.

       int strcoll(const char *s1, const char *s2);
	      Compare the strings s1 with s2 using the current locale.

       char *strcpy(char *dest, const char *src);
	      Copy the string src to dest, returning a pointer to the start of
	      dest.

       size_t strcspn(const char *s, const char *reject);
	      Calculate	 the  length  of  the  initial segment of the string s
	      which does not contain any of bytes in the string reject,

       char *strdup(const char *s);
	      Return a duplicate of the string s  in  memory  allocated	 using
	      malloc(3).

       char *strfry(char *string);
	      Randomly swap the characters in string.

       size_t strlen(const char *s);
	      Return the length of the string s.

       char *strncat(char *dest, const char *src, size_t n);
	      Append  at  most	n characters from the string src to the string
	      dest, returning a pointer to dest.

       int strncmp(const char *s1, const char *s2, size_t n);
	      Compare at most n bytes of the strings s1 and s2.

       char *strncpy(char *dest, const char *src, size_t n);
	      Copy at most n bytes  from  string  src  to  dest,  returning  a
	      pointer to the start of dest.

       char *strpbrk(const char *s, const char *accept);
	      Return  a pointer to the first occurrence in the string s of one
	      of the bytes in the string accept.

       char *strrchr(const char *s, int c);
	      Return a pointer to the last occurrence of the  character	 c  in
	      the string s.

       char *strsep(char **stringp, const char *delim);
	      Extract the initial token in stringp that is delimited by one of
	      the bytes in delim.

       size_t strspn(const char *s, const char *accept);
	      Calculate the length of the starting segment  in	the  string  s
	      that consists entirely of bytes in accept.

       char *strstr(const char *haystack, const char *needle);
	      Find  the first occurrence of the substring needle in the string
	      haystack, returning a pointer to the found substring.

       char *strtok(char *s, const char *delim);
	      Extract tokens from the string s that are delimited  by  one  of
	      the bytes in delim.

       size_t strxfrm(char *dest, const char *src, size_t n);
	      Transforms  src  to  the	current	 locale and copies the first n
	      characters to dest.

DESCRIPTION
       The string  functions  perform  string  operations  on  null-terminated
       strings.	  See  the individual man pages for descriptions of each func‐
       tion.
