Function Documentation

int ascopy (  asid_t  from_asid, char *  from_buf, asid_t  to_asid, char *  to_buf, size_t  len )

int copy (  pid_t  from_pid, char *  from_buf, pid_t  to_pid, char *  to_buf, size_t  len )

Copies bytes from one process to another. Don't forget that as in any string manipulating function, the buffer that shall receive the copy *MUST* be allocated with a size of <len>. Parameters: from_pid  The pid of the process we want to read from. from_buf  The pointer to the data we want to copy. to_pid  The pid of the process we want to write to. Generally, you'll want to put -1 to write to your own process. to_buf  The pointer to the zone we want to copy to. len  The number of bytes we want to copy. Returns: The number of bytes copied, or -1 if a problem happened.

int copyinstr (  pid_t  from_pid, char *  from_str, char *  to_str, size_t  max_len )

copy max_len bytes from from_pid's aspace. A final 0 is automatically appended, for this to work, to_str must have a length of max_len+1.
