Yes... That's the way I read the description of the function:

memcpy
memcpypgm
memcpypgm2ram
memcpyram2pgm

Function: Copy the contents of the source buffer into the destination buffer.
Include: string.h

Prototype:
void * memcpy(void * dest, const void * src, size_t memsize );
rom void * memcpypgm(rom void * dest, const rom void * src, sizerom_t
memsize );
void * memcpypgm2ram(void * dest, const rom void * src, sizeram_t memsize );
rom void * memcpyram2pgm(rom void * dest,const void * src,sizeram_t
memsize );

Arguments: dest Pointer to destination array.
src Pointer to source array.
memsize Number of bytes of src array to copy into dest.

Remarks: This function copies the first memsize number of bytes in src to
the array dest. If src and dest overlap, the behavior is undefined.

Return Value: This function returns the value of dest.

File Names: memcpy.asm
memcpyp2p.asm
memcpyp2r.asm
memcpyr2p.asm
