  • Memmove function in C

    Memmove function in C

     void function * memmove (void * str1, const void * str2, size_t n) copy n characters from str2 to str1, but to solve the matching of memory blocks, memmove () is a safe approach more than memcpy ().
  • Memset () function in C

    Memset () function in C

     the function void * memset (void * str, int c, size_t n) copies the character c (an unsigned char) to the first n characters of the string pointed to by parameter str.
  • Strcat function in C

    Strcat function in C

     the char * strcat function (char * dest, const char * src) append the string pointed to by src, at the end of the string pointed to by dest.
  • The function strcmp () in C

    The function strcmp () in C

     the function int strcmp (const char * str1, const char * str2) compares the string pointed to by sr1 with the string pointed to by srt2.
  • The function strncmp () in C

    The function strncmp () in C

     the function int strncmp (const char * str1, const char * str2, size_t n) compares the first n bytes of str1 and str2.
  • The strcoll () function in C

    The strcoll () function in C

     the function int strcoll (const char * str1, const char * str2) compares strings str1 and str2. the result depends on setting lc_collate.
  • Strcpy () function in C

    Strcpy () function in C

     char * strcpy function (char * dest, const char * src) copies the string pointed to by src to dest.
  • The function strpbrk () in C

    The function strpbrk () in C

     char * strpbrk (const char * str1, const char * str2) finds the first character in str1 string that connects any character specified in str2. (not including null ending characters).
  • The strrchr () function in C

    The strrchr () function in C

     char * strrchr (const char * str, int c) looks for the last occurrence of the character c (an unsigned char) in the string pointed to by parameter str.
  • The strspn () function in C

    The strspn () function in C

     function size_t strspn (const char * str1, const char * str2) calculates the length of the first character segment of the str1 string containing the characters in str2
  • The strtok () function in C

    The strtok () function in C

     char * strtok function (char * str, const char * delim) divides the string str into a sequence of tokens separately separated by delim separators (eg comma, ...).
  • Function strxfrm () in C

    Function strxfrm () in C

     the function size_t strxfrm (char * dest, const char * src, size_t n) transforms the first n characters of the src string into the current locale and places them in dest string.
