Random Access to Text Lines in Files

Functions

Function	Description
`_lc_byte_at`	Internal byte reader helper.
`_lc_open`	Internal: read file via syscalls.
`_lc_read`	Internal: read from fd.
`_lc_close`	Internal: close fd.
`linecache_open`	Open a file and index its lines. Layout: [0]=line_count, [1]=data_ptr, [2]=da…
`linecache_getline`	Get a line by number (1-based). Returns length, -1 if out of range.
`linecache_count`	Return total number of lines.
`linecache_close`	Release linecache (no-op in Jda — no GC, no free).

fn _lc_byte_at(buf: &i8, idx: i64) -> i64

Internal byte reader helper.

fn _lc_open(path: &i8) -> i64

Internal: read file via syscalls.

fn _lc_read(fd: i64, buf: &i8, max: i64) -> i64

Internal: read from fd.

fn _lc_close(fd: i64) -> i64

Internal: close fd.

fn linecache_open(path: &i8) -> &i64

Open a file and index its lines. Layout: [0]=line_count, [1]=data_ptr, [2]=data_len, [3]=offsets_ptr, [4]=lengths_ptr

fn linecache_getline(lc: &i64, lineno: i64, out: &i8) -> i64

Get a line by number (1-based). Returns length, -1 if out of range.

fn linecache_count(lc: &i64) -> i64

Return total number of lines.

fn linecache_close(lc: &i64) -> i64

Release linecache (no-op in Jda — no GC, no free).
