Posted on May 17, 2011 at 11:35 we want to better understand external memory access and usage when writing in C.
If I create a the following (using the large C model):
char szString1[50000];
char szString2[50000];
the compiler/linker will put them in different segements.
Now I will do:
memcpy(&szString1[400], szString2);
Will this work or do I need to manage the paging myself.
The important issue to understand is who is responsible to manage the paging of the external memory with regard to segmentation.
Does the system handle correct address passing and actual management when using pointers to variables in the data segment, stack and stack of interrupt routines
