This repo is a libified version of par2cmdline. It tracks that source line for line, but instead of the commandline application, you obtain a shared library, ready for easy inclusion in your own applications.
At this time, ./compile.sh produces a .so on Unix platforms. ./wincompile.sh creates a Windows DLL using the mingw compiler (sudo apt install mingw-w64). Pull requests for macOS compiling instructions and binaries welcome!
I found no way easy to turn par2cmdline into a library, and after a long and unpleasant struggle with automake an libtool, I decided to simply not use the existing (auto)makefile, nor letting the linker sort out includes and symbol availability, but do it (nearly) the SQLite way and simply include all source into a single file.
This library exposes a single function, par2cmdline, which takes int,char** parameters. These are, you guessed it, exactly what you would pass to the par2 command. Let's say you would want the equivalent of par2 c -r5 -n1 music.mp3, then call par2cmdline as follows:
const char* cmds[4] = {"c", "-r5", "-n1", "music.mp3"};
par2cmdline(4,cmds);
Isn't it marvelous?
Because it is not in the par2cmdline readme, I'll save you some code digging and report below the possible par2cmdline return values:
0: Succes.
1: Repairable damage found.
2: Irreparable damage found.
3: Invalid commandline arguments.
4: Parity file unusable.
5: Repair failed.
6: IO error.
7: Internal error.
8: Out of memory.
- None :)
- 2020-04-25: v0.8.1. First release of libpar2. I'll follow
par2cmdlineversioning.
