Function Documentation

int little_endian (   )

Check whether current platform uses little endian byte order. See H&S Sec. 6.1.2 pp. 163-4. Returns: Returns 1, if current platform is little endian, and 0 if not.

void printf32bits (  void *  buf  )

void swabip (  void *  buf, int  size )

In-place swab, replaces the non-ANSI function swab(), which may not work if data is overlapping. Parameters: buf  Pointer to memory size  Size of buf in bytes

void swap (  void *  from, void *  to, int  size )

Swaps the specified short int, int, long int, float, or double from little endian to big endian or vice versa. Arguments are allowed to overlap. Parameters: from  Pointer to a short int, int, long int, float, or double variable to  Pointer to a short int, int, long int, float, or double variable size  Size of from and to (byte nr) must be 1, 2, 4 or 8.

void swawbip (  void *  buf, int  size )

In-place swab and swaw, switches words and bytes from an array of 4-byte ints or floats. Parameters: buf  Pointer to memory size  Size of buf in bytes

void swawip (  void *  buf, int  size )

In-place swaw, switches words (but not bytes) from an array of 4-byte ints or floats. Parameters: buf  Pointer to memory size  Size of buf in bytes
