PA_SetBlobVariable (aVariable; newBlob; size)
| Parameter | Type | Description | |
| aVariable | PA_Variable * |  | Pointer to the variable to access |
| newBlob | void * | | New value for aVariable |
| size | long | | Size (in bytes) of newBlob |
Description
The routine PA_SetBlobVariable sets the content of the BLOB variable pointed to by aVariable to the data pointed to by newBlob.
Pass a pointer to the new data value in newBlob and its size in size.
WARNING
The kind of of the variable pointed to by aVariable is set to eVK_Blob by the routine, even if it was not its previous kind.
Make sure that you do not change 4D variable kinds (using PA_GetVariable), especially in compiled mode.
Note that PA_SetBlobVariable duplicates newBlob, which still belongs to the plug-in after the call. To give the data without duplicating it, use PA_SetBlobHandleVariable.
