Arguments

addr_dest

Lowest CPU memory address to copy/decode source address’s data value.

...

Since octet-order copy/conversion are inverse operations, MEM_VAL_COPY_GET_xxx() and MEM_VAL_COPY_SET_xxx() memory data-copy get/set macros are inverse, but identical, operations and are provided in both forms for semantics and consistency.

Example Usage

Code Block
languagecpp
          CPU_INT16U  *pmem;
          CPU_INT16U  *pval;
          CPU_INT08U   buf[SIZE];


          pmem = &SomeAddr;                    /* Any CPU address */
          pval = &SomeVal;                     /* Any CPU address */
          MEM_VAL_COPY_GET_INT16U(pmem, pval);
          MEM_VAL_COPY_GET_INTU(&buf[0], pmem, sizeof(buf));
