PCMCIA_IS_WRITE_PROTECTED callback function (ntddpcm.h)
The PCMCIA_IS_WRITE_PROTECTED interface routine returns the write-protect condition of a PCMCIA memory card.
Syntax
PCMCIA_IS_WRITE_PROTECTED PcmciaIsWriteProtected;
BOOLEAN PcmciaIsWriteProtected(
[in, optional] PVOID Context
)
{...}
Parameters
[in, optional] Context
Pointer to the context for the interface routine.
Return value
The PCMCIA_IS_WRITE_PROTECTED interface routine returns TRUE if the memory card is write-protected, otherwise it returns FALSE.
Remarks
A caller must set the Context parameter to the context that is specified by the PCMCIA bus driver. The PCMCIA bus driver returns the context for the interface routines in the Context member of the same PCMCIA_INTERFACE_STANDARD structure that contains the pointers to the interface routines. If the Context parameter is not valid, system behavior is not defined, and the system might halt.
Callers of this routine must be running at IRQL <= DISPATCH_LEVEL. To maintain overall system performance, it is recommended that drivers call this routine at IRQL < DISPATCH_LEVEL.
