Fixed bug in mvhd_sparse_read (needed an fseek after doing memset(buff, 0, MVHD_SECTOR_SIZE)). Added progress callbacks to the mvhd_create_* functions. Converted all use of ftello64 and fseeko64 to new portable versions: mvhd_ftello64 and mvhd_fseeko64. Addes some explicit casts and other fixes to remove compiler warnings.
MiniVHD - Minimalist VHD implementation in C
MiniVHD is a minimalist implementation of read/write/creation of VHD files. It is designed to read and write to VHD files at a sector level. It does not enable file access, or provide mounting options. Those features are left to more advanced libraries and/or the OS.
Features
MiniVHD aims to implement as much of the VHD specification as possible. Features include:
- Implemented in pure C. Some C99 features are used (such as stdint, stdbool, array initialisation), so not compatible with strict ANSI C
- Full support for fixed, sparse (dynamic) and differencing VHD images
- Open existing VHD images
- VHD image creation
- Conversion to/from raw disk images
- Read/write sectors to VHD images
- Aims to be cross platform, although not fully there yet. Works with MinGW-w64, and presumably GCC/Clang
- Simple to include and use (I hope)
Usage
Drop the source code in your project, and add the C files to your build system. No compiler flags are required.
Include minivhd.h in your source to get started. See minivhd.h for documentation of the API.
Please note, an older version of this library can be found in the minivhd-v1 branch of this repository, if required for some reason.
