Function esp_idf_sys::i2c_cmd_link_create_static

pub unsafe extern "C" fn i2c_cmd_link_create_static(
    buffer: *mut u8,
    size: u32
) -> i2c_cmd_handle_t

@brief Create and initialize an I2C commands list with a given buffer. All the allocations for data or signals (START, STOP, ACK, …) will be performed within this buffer. This buffer must be valid during the whole transaction. After finishing the I2C transactions, it is required to call i2c_cmd_link_delete_static().

@note It is highly advised to not allocate this buffer on the stack. The size of the data used underneath may increase in the future, resulting in a possible stack overflow as the macro I2C_LINK_RECOMMENDED_SIZE would also return a bigger value. A better option is to use a buffer allocated statically or dynamically (with malloc).

@param buffer Buffer to use for commands allocations @param size Size in bytes of the buffer

@return Handle to the I2C command link or NULL if the buffer provided is too small, please use I2C_LINK_RECOMMENDED_SIZE macro to get the recommended size for the buffer.
