package octez-proto-libs

sub src ofs len extract a sub-array of src starting at ofs and of length len. No copying of elements is involved: the sub-array and the original array share the same storage space.

blit src ofs_src dst ofs_dst len copy len bytes from src starting at ofs_src into dst starting at ofs_dst.

of_string s create an byte array filled with the same content than s.

to_string b dump the array content in a string.

sub_string b ofs len is equivalent to to_string (sub b ofs len).

get_char buff i reads 1 byte at offset i as a char

get_uint8 buff i reads 1 byte at offset i as an unsigned int of 8 bits. i.e. It returns a value between 0 and 2^8-1

get_int8 buff i reads 1 byte at offset i as a signed int of 8 bits. i.e. It returns a value between -2^7 and 2^7-1

set_char buff i v writes v to buff at offset i

set_int8 buff i v writes the least significant 8 bits of v to buff at offset i

get_uint16 buff i reads 2 bytes at offset i as an unsigned int of 16 bits. i.e. It returns a value between 0 and 2^16-1

get_int16 buff i reads 2 byte at offset i as a signed int of 16 bits. i.e. It returns a value between -2^15 and 2^15-1

get_int32 buff i reads 4 bytes at offset i as an int32.

get_int64 buff i reads 8 bytes at offset i as an int64.

set_int16 buff i v writes the least significant 16 bits of v to buff at offset i

set_int32 buff i v writes v to buff at offset i

set_int64 buff i v writes v to buff at offset i
