hwi_alloc_item()

QNX SDP8.0Building Embedded SystemsConfigurationDeveloper

Add an item structure to the system page hwinfo section.

Synopsis:

void *hwi_alloc_item(const char *tagname, 
                     unsigned size, 
                     unsigned align, 
                     const char *itemname, 
                     unsigned owner);

Arguments:

tagname
The name of the tag to add.
size
The size, in bytes, of the tag to allocate.
align
Ensure the structure is correctly aligned. If the structure contains any 64-bit integer fields, set align to 8; otherwise, set it to 4.
itemname
The name of the item to add.
owner
The item that owns this item (that is, the parent; see Items).

Description:

This function allocates an item structure. Its first three arguments are the same as in the hwi_alloc_tag() function. The itemname and owner arguments are used to set the itemname and owner fields of the hwi_item structure.

All hwi_alloc_tag() calls done after a hwi_alloc_item() call are assumed to belong to that item, and the itemsize field is adjusted accordingly.

Returns:

>0
Success: a pointer to a location in memory that can be filled in as appropriate.
