Function pt_iscache_read

pub unsafe extern "C" fn pt_iscache_read(
    iscache: *mut pt_image_section_cache,
    buffer: *mut u8,
    size: u64,
    isid: c_int,
    vaddr: u64,
) -> c_int

Read memory from a cached file section

Reads @size bytes of memory starting at virtual address @vaddr in the section identified by @isid in @iscache into @buffer.

The caller is responsible for allocating a @buffer of at least @size bytes.

The read request may be truncated if it crosses section boundaries or if @size is getting too big. We support reading at least 4Kbyte in one chunk unless the read would cross a section boundary.

Returns the number of bytes read on success, a negative error code otherwise.

Returns -pte_invalid if @iscache or @buffer is NULL. Returns -pte_invalid if @size is zero. Returns -pte_nomap if @vaddr is not contained in section @isid. Returns -pte_bad_image if @iscache does not contain @isid.
