int bcmp(const void &sstarf#star;ptr1, const void &sstarf#star;ptr2, size_t no); Compare no of bytes at position ptr1 with ptr2.
void bcopy(const void &sstarf#star;src, void &sstarf#star;dst, size_t len); Copy len bytes from position src to dst.
void bzero(void &sstarf#star;dst, size_t len); Set len bytes at position dst to 0.
char &sstarf#star;index(const char &sstarf#star;str, int charw); char &sstarf#star;rindex(const char &sstarf#star;str, int charw); Same as strchr() (strrchr()).
void &sstarf#star;memccpy(void &sstarf#star;dst, const void &sstarf#star;src, int ucharstop, size_t no); Copy characters from src to dst until character ucharstop, but copy at most no bytes.
void &sstarf#star;memchr(const void &sstarf#star;ptr, int ucharwanted, size_t no); Find character ucharwanted in area at ptr, but compare at most no character.
int memcmp(const void &sstarf#star;ptr1, const void &sstarf#star;ptr2, size_t no); Compare no bytes from memory area at ptr1 with area at ptr2.
void &sstarf#star;memcpy(void &sstarf#star;dst, const void &sstarf#star;src, size_t no); Copy no of bytes from area at src to dst.
void &sstarf#star;memset(void &sstarf#star;ptr, int ucharfill, size_t no); Set no of bytes at position ptr to character ucharfill.
char &sstarf#star;strcat(char &sstarf#star;dst, const char &sstarf#star;src); char &sstarf#star;strncat(char &sstarf#star;dst, const char &sstarf#star;src, size_t no); Concatenate the string at src to the string at dst. strncat() concatenates at most no characters.
char &sstarf#star;strchr(const char &sstarf#star;str, int charw); char &sstarf#star;strrchr(const char &sstarf#star;str, int charw); Find first (last) occurence of character charw in string str.
int strcmp(const char &sstarf#star;str1, const char &sstarf#star;str2); int strncmp(const char &sstarf#star;str1, const char &sstarf#star;str2, size_t no); Compare string str1 with string str1. strncmp() compares at most no characters.
char &sstarf#star;strcpy(char &sstarf#star;dst, const char &sstarf#star;src); char &sstarf#star;strncpy(char &sstarf#star;dst, const char &sstarf#star;src, size_t no); Copy string at src to dst. strncpy() copies at most sl no characters.
