write_sel_addr

Syntax

#include <debug/dbgcom.h> void write_sel_addr (unsigned sel, unsigned offset, void *buf, unsigned len);

Description

This function transfers len bytes from the buffer pointed to by buf in the data segment whose selector is sel, at offset offset. The companion function read_sel_addr (see section read_sel_addr) is usually called before write_sel_addr to save the original contents, if needed.

Return Value

The function return zero if it has successfully transferred the data, non-zero otherwise (e.g., if the address in offset is outside the limits of the sels segment).
