void _dbus_verbose_bytes_of_string(const DBusString *str, int start, int len)
Dump the given part of the string to verbose log.
int dbus_int32_t
A 32-bit signed integer on all platforms.
dbus_bool_t _dbus_string_insert_2_aligned(DBusString *str, int insert_at, const unsigned char octets[4])
Inserts 2 bytes aligned on a 2 byte boundary with any alignment padding initialized to 0...
#define DBUS_UINT64_CONSTANT(val)
Declare a 64-bit unsigned integer constant.
int _dbus_type_get_alignment(int typecode)
Gets the alignment requirement for the given type; will be 1, 4, or 8.
dbus_bool_t _dbus_string_insert_alignment(DBusString *str, int *insert_at, int alignment)
Inserts padding at *insert_at such to align it to the given boundary.
const char * _dbus_string_get_const_data(const DBusString *str)
Gets the raw character buffer from a const string.
void _dbus_string_init_const_len(DBusString *str, const char *value, int len)
Initializes a constant string with a length.
dbus_bool_t _dbus_marshal_set_basic(DBusString *str, int pos, int type, const void *value, int byte_order, int *old_end_pos, int *new_end_pos)
Sets an existing basic type value to a new value.
dbus_uint32_t u32
as int32
#define _DBUS_DOUBLES_BITWISE_EQUAL(a, b)
On x86 there is an 80-bit FPU, and if you do "a == b" it may have a or b in an 80-bit register...
unsigned short dbus_uint16_t
A 16-bit unsigned integer on all platforms.
dbus_bool_t _dbus_marshal_write_basic(DBusString *str, int insert_at, int type, const void *value, int byte_order, int *pos_after)
Marshals a basic-typed value.
#define DBUS_LITTLE_ENDIAN
Code marking LSB-first byte order in the wire protocol.
void _dbus_verbose_bytes(const unsigned char *data, int len, int offset)
If in verbose mode, print a block of binary data.
dbus_uint32_t _dbus_marshal_read_uint32(const DBusString *str, int pos, int byte_order, int *new_pos)
Convenience function to demarshal a 32 bit unsigned integer.
