SysPciWriteValue
(FUN)
FUNCTION SysPciWriteValue : RTS_IEC_RESULT
<description>Write one PCI config value This function allows to set single configuration values of a PCI card via a pointer on the corresponding memory address (pbyData). Therefore the bus entry associated to the PCI card is identified via the bus, device and function number. The bus entry is a structure of type PCI_INFO. The component to be read out is indicated by PciOffset. </description> <result><p>RESULT: Returns the runtime system error code (see CmpErrors.library).</p></result>
