Type:bool

Parameter:

TypeParameterName

301  pos = pointer to current position in the buffer
303  If pack_nameX - check is the next element is of type X with a name of @name*@e: serialized data extent information (NOT NULL)*@code: type code*@name: name to match to the serialized element Then
304  If Not st if read will be in packed data bounds Then Go to fail
306  If data Then data = get value from possibly mis-aligned location((u8 * )pointer to current position in the buffer )
308  pointer to current position in the buffer += sizeof(u8)
309  Return 1
