# NSPR emulation library
|
|
|
|
Author: Max Bolingbroke (<batterseapower@hotmail.com>)
|
|
|
|
This library was created by pulling together the minimal pieces of NSPR required to get the Universal Character Set
|
|
Detector (UCSD) to compile. It turns out that the UCSD uses only very minimal parts of NSPR, so we can get away with just a few
|
|
header files and totally forget about linking to the library.
|
|
|
|
Precisely, we used these files from [NSPR v4.8.6](https://ftp.mozilla.org/pub/mozilla.org/nspr/releases/v4.8.6/):
|
|
|
|
* prtypes.h
|
|
* prmem.h
|
|
* obsolete/protypes.h
|
|
|
|
I then patched some prototypes in prmem.h to use C library functions directly. The protypes were replaced with #define directives
|
|
that ensure that callers of PR_Malloc, PR_Calloc, PR_Realloc, PR_Free just use their C library counterparts directly.
|
|
|
|
To finish off, I needed to provide prcpucfg.h. Normally this is generated by the nspr build process, but to simplify things I used
|
|
the version from [Google's Chrome source tree](http://src.chromium.org/viewvc/chrome/trunk/src/base/third_party/nspr/prcpucfg.h?view=markup)
|
|
that just uses the preprocessor to choose between several pre-generated versions.
|
|
|
|
I had to patch the Google-provided prcpucfg.h so that the #included paths pointed to the right directory.

## Licensing
|
|
|
|
Chromium (and thus presumably their contribution) is licensed under the BSD license.
|
|
|
|
NSPR is licensed under the MPL/GPL/LGPL tri-license.
|
|
|
|
Thus, this emulation library is licensed under the LGPL (I think). |
