- ***** A Word about Model Dependent Function Naming Convention ***********
- *************************************************************************/
-
- /*
- NSPR 2.0 must implement its function across a range of platforms
- including: MAC, Windows/16, Windows/95, Windows/NT, and several
- variants of Unix. Each implementation shares common code as well
- as having platform dependent portions. This standard describes how
- the model dependent portions are to be implemented.
-
- In header file pr/include/primpl.h, each publicly declared
- platform dependent function is declared as:
-
- PR_EXTERN void _PR_MD_FUNCTION( long arg1, long arg2 );
- #define _PR_MD_FUNCTION _MD_FUNCTION
-
- In header file pr/include/md/<platform>/_<platform>.h,
- each #define'd macro is redefined as one of:
-
- #define _MD_FUNCTION <blanks>
- #define _MD_FUNCTION <expanded macro>
- #define _MD_FUNCTION <osFunction>
- #define _MD_FUNCTION <_MD_Function>
-
- Where:
-
- <blanks> is no definition at all. In this case, the function is not implemented
- and is never called for this platform.
- For example:
- #define _MD_INIT_CPUS()
-
- <expanded macro> is a C language macro expansion.
- For example:
- #define _MD_CLEAN_THREAD(_thread) \
- PR_BEGIN_MACRO \
- PR_DestroyCondVar(_thread->md.asyncIOCVar); \
- PR_DestroyLock(_thread->md.asyncIOLock); \
- PR_END_MACRO
-
- <osFunction> is some function implemented by the host operating system.
- For example:
- #define _MD_EXIT exit
-
- <_MD_function> is the name of a function implemented for this platform in
- pr/src/md/<platform>/<soruce>.c file.
- For example:
- #define _MD_GETFILEINFO _MD_GetFileInfo
-
- In <source>.c, the implementation is:
- PR_IMPLEMENT(PRInt32) _MD_GetFileInfo(const char *fn, PRFileInfo *info);
