# `omath::SectionScanResult` — File-based pattern scan result
|
|
|
|
> Header: `omath/utility/section_scan_result.hpp`
|
|
> Namespace: `omath`
|
|
> Depends on: `<cstddef>`, `<cstdint>`
|

|
|
`SectionScanResult` is the return type for file-based pattern scans across all binary formats (PE, ELF, Mach-O). It carries the section's virtual and raw base addresses together with the offset to the matched pattern.
|

|
## API
|
|
|
|
```cpp
|
|
namespace omath {
|
|
|
|
struct SectionScanResult final {
|
|
std::uintptr_t virtual_base_addr; // virtual address base of the scanned section
|
|
std::uintptr_t raw_base_addr; // file offset of the section start
|
|
std::ptrdiff_t target_offset; // offset from section base to the first matched byte
|
|
};
|
|
|
|
} // namespace omath
|
|
```
|
|
|
|

|
## Computing addresses from a result
|
|
|
|
```cpp
|
|
omath::SectionScanResult res = /* ... */;
|
|
|
|
// Virtual address of the match (as if the binary were loaded at its preferred base)
|
|
auto va_hit = res.virtual_base_addr + res.target_offset;
|
|
|
|
// Raw file offset of the match
|
|
auto raw_hit = res.raw_base_addr + res.target_offset;
|
|
```

## Notes
|
|
|
|
* `virtual_base_addr` is computed from the section header (RVA for PE, `sh_addr` for ELF, `addr` for Mach-O).
|
|
* `raw_base_addr` is the file offset where the section data begins on disk.
|
|
* `target_offset` is always relative to the section base — add it to either address to locate the match.
