# GX_LoadTexEx

## C Specification

      #include <nitro/gx/gx_load.h>

      void GX_LoadTexEx(
      GXVRamTex tex,
      const void *pSrc,
      u32 destSlotAddr,
      u32 szByte
      );

## Arguments

tex | Texture image slot setting
pSrc | Pointer to transfer origin
destSlotAddr | Address in transfer destination texture image slot
szByte | Transfer size (in bytes)

## Return Values

None.

## Description

This function uses DMA to transfer texture images to VRAM banks that can be allocated to texture image slots. The transfer destination address (in the texture image slot) can be specified. The DMA channel that is used is `GX_DMAID` (defined in `gxcommon.h`). Both `destSlotAddr` and `szByte` must be 4-byte aligned.
Notes: Because the DMA transfer is carried out internally, the transfer source data must be flushed to the main memory using a function such as `DC_FlushRange` prior to the process. If the regions for transfer source and transfer destination overlap, the operation result is undefined. The VRAM bank specified by `tex` must be mapped in LCDC space.
