NTFS_RL_REPLACE

NAME

SYNOPSIS

runlist_element * ntfs_rl_replace (runlist_element * dst, int dsize, runlist_element * src, int ssize, int loc);  

ARGUMENTS

dst

original runlist to be worked on

dsize

number of elements in dst (including end marker)

src

new runlist to be inserted

ssize

number of elements in src (excluding end marker)

loc

index in runlist dst to overwrite with src

DESCRIPTION

Replace the runlist element dst at loc with src. Merge the left and right ends of the inserted runlist, if necessary.

It is up to the caller to serialize access to the runlists dst and src.

On success, return a pointer to the new, combined, runlist. Note, both runlists dst and src are deallocated before returning so you cannot use the pointers for anything any more. (Strictly speaking the returned runlist may be the same as dst but this is irrelevant.)

On error, return -errno. Both runlists are left unmodified. The following  

ERROR CODES ARE DEFINED

-ENOMEM - Not enough memory to allocate runlist array. -EINVAL - Invalid parameters were passed in.
