Detailed Description

Experimental API header Conversions between different number representations.

MySQL writes binary data in LE, therefore this header defines the following conversions: host -> LE (for writing) LE -> host (for reading)

Function Documentation

htole64()

uint64_t htole64 ( uint64_t  x )

inline

Converting a 64 bit integer from host's byte order to little-endian byte order.

Parameters

Returns

64-bit integer in little endian byte order

le64toh()

uint64_t le64toh ( uint64_t  x )

inline

Converting a 64 bit integer from little-endian byte order to host byteorder.

Parameters

x	64-bit integer in little endian byte order

Returns

64-bit integer in host byte order
