    clive1 is correct as ever. But anyway the idea is that for example,

    PC0 ADC123_IN10

    means that PC0 can be the input pin for ADC channel 10 and you can use ADC 1, 2 or 3 to measure it. You have to set up the pin function and the multiplexer all in software. Not all channels are connected to all ADCs. Look at the Figure 1. STM32F103xC, STM32F103xD and STM32F103xE performance line block diagram in the data sheet (or whatever is applicable for your device) to see a diagram which helps explain.
