Routine Description:

Arguments:

|
|
pclConflictList - holds returned conflict list handle
|
|
dnDevInst Device we want to allocate a resource for
|
|
ResourceID Type of resource, ResType_xxxx

|
|
ResourceLen length of ResourceData
|
|
|
|
ulFlags Width of certain variable-size resource
|
|
descriptor structure fields, where applicable.
|
|
|
|
Currently, the following flags are defined:
|
|
|
|
CM_RESDES_WIDTH_32 or
|
|
CM_RESDES_WIDTH_64
|
|
|
|
If no flags are specified, the width of the variable-sized

resource data supplied is assumed to be that native to the

|
platform of the caller.

hMachine - optional machine to query
