View source for CM ALLOCDETAILFIELDINFO

This message allocates memory for one or more [[FIELDINFO]] structures.
==Syntax==
<PRE>
param1
USHORT nFieldInfo;   /* Number of FIELDINFO structures to be allocated. */

param2
ULONG ulReserved;    /* Reserved value, should be 0. */
</PRE>

==Parameters==
;nFieldInfo ([[USHORT]]) - Input
: Number of [[FIELDINFO]] structures to be allocated.
: The value of this parameter must be greater than 0.
;ulReserved ([[ULONG]]) - Input
: Reserved value, should be 0.

==Returns==
;pFieldInfo (P[[FIELDINFO]]) - returns
: Pointer or error.
::0: Reserved value, 0. The [[WinGetLastError]] function may return the following errors:
:::PMERR_INSUFFICIENT_MEMORY
:::PMERR_INVALID_PARAMETERS
::Other: If the '''nFieldInfo''' parameter has a value of 1, a pointer to a [[FIELDINFO]] data structure is returned.
::A pointer to the first [[FIELDINFO]] structure in a linked list of [[FIELDINFO]] structures is returned if the '''nFieldInfo''' parameter has a value greater than 1. The pointer to the next [[FIELDINFO]] structure is set in each '''pNextFieldInfo''' field of the [[FIELDINFO]] data structure. The last pointer is set to NULL.

==Remarks==
The container control requires that the application use the CM_ALLOCDETAILFIELDINFO message to allocate memory for any [[FIELDINFO]] structures that are used.

==Default Processing==
The default window procedure does not expect to receive this message and therefore takes no action on it other than to return NULL.
