Function Documentation

void bcopy (  const void *  in, void *  out, size_t  n )

Copy the first n bytes from in to out. The buffers may overlap.

void bzero (  void *  b, size_t  length )

Clear the first length bytes of b

void* memchr (  const void *  src, int  c, size_t  length )

Search a byte in the first length bytes of a buffer and returns a pointer to it in the buffer or NULL if not present.

int memcmp (  const void *  s1, const void *  s2, size_t  n )

Compare the first n bytes of two buffers and returns the lexicographic order.

void* memcpy (  void *  out, const void *  in, size_t  n )

Copy the first n bytes from in to out. The buffers may overlap. Returns out.

void* memmove (  void *  dst, const void *  src, size_t  length )

Copy the first n bytes from in to out. The buffers may overlap. Returns out.

void* memset (  const void *  dst, int  c, size_t  length )

Set the first length bytes of dst to the character c

char* strcat (  char *  dst, const char *  src )

Append the src string at the end of the dst string

char* strchr (  const char *  string, int  c )

Search a character in a string from left to right and returns a pointer to it in the string or NULL if not present.

int strcmp (  const char *  a, const char *  b )

Alphabetical order of string a and b.

char* strcpy (  char *  dst, const char *  src )

Copy the src string in the dst string. Returns a pointer to the end of the copy.

size_t strlen (  const char *  str  )

Compute the length of the string (terminated by a null byte)

char* strncat (  char *  dst, const char *  src, size_t  length )

Append the first length characters (or less) of the src string at the end of the dst string.

int strncmp (  const char *  a, const char *  b, size_t  length )

Alphabetical order of at most the length first characters of a and b.

char* strncpy (  char *  dst, const char *  src, size_t  length )

Copy at most length character of src string in dst string. Returns a pointer to the end of the copy.

char* strrchr (  const char *  string, int  c )

Search a character in a string from right to left and returns a pointer to it in the string or NULL if not present.
