LPFNIG_MEM

Create a function of this type to give your application the flexibility of replacing ImageGear's memory allocation routine with your own.

Declaration:

	Copy Code
typedef LPBYTE (ACCUAPI LPFNIG_MEM_ALLOC)(AT_UINT nSize);

Arguments:

Name	Type	Description
nSize	AT_UINT	Number of bytes to allocate.

Return Value:

The user supplied callback function should return a pointer to the allocated block of memory.

Supported Raster Image Formats:

This function does not process image pixels.

Example:

	Copy Code
/*************************************************************/ / Memory Alloc callback function definition / /***********************************************************/ LPBYTE ACCUAPI MyMemAlloc(AT_UINT nSize) / number of bytes to alloc/ { / Put your own memory allocation code here / return( buffer); }; /See also example for IG_mem_CB_register() */

Copy Code

/**************************************************************/
/* Memory Alloc callback function definition */
/*************************************************************/
LPBYTE  ACCUAPI MyMemAlloc(AT_UINT nSize) /* number of bytes to alloc*/
{
        /* Put your own memory allocation code here */
        return( buffer);
};
/*See also example for IG_mem_CB_register() */

Remarks:

This callback function is registered by calling IG_mem_CB_register(). The register function must be called prior to any user-defined callback functions being used by the ImageGear library.

Your memory allocation function will only be used when large allocations (allocations greater than 1024) are performed.
