From 79621f3e4151dfe8ef8fdb2800c59dc65f4867e6 Mon Sep 17 00:00:00 2001 From: Taylor Blau Date: Thu, 23 May 2024 17:26:49 -0400 Subject: pack-bitmap: extract `read_bitmap()` function The pack-bitmap machinery uses the `read_bitmap_1()` function to read a bitmap from within the mmap'd region corresponding to the .bitmap file. As as side-effect of calling this function, `read_bitmap_1()` increments the `index->map_pos` variable to reflect the number of bytes read. Extract the core of this routine to a separate function (that operates over a `const unsigned char *`, a `size_t` and a `size_t *` pointer) instead of a `struct bitmap_index *` pointer. This function (called `read_bitmap()`) is part of the pack-bitmap.h API so that it can be used within the upcoming portion of the implementation in pseduo-merge.ch. Rewrite the existing function, `read_bitmap_1()`, in terms of its more generic counterpart.
