4815	dependency on obsolete versions of mmap and shmdt	stephen.clamage@…	Ion Gaztañaga	"Compiler error messages when compiling on Solaris: [[br]]
""../../../boost/interprocess/mapped_region.hpp"", line 549: Error: Formal argument 1 of type char* in call to shmdt(char*) is being passed void*. [[br]]
""../../../boost/interprocess/anonymous_shared_memory.hpp"", line 87: Error: Formal argument 1 of type char* in call to mmap(char*, unsigned, int, int, int, long) is being passed void*.

The problem is that the calls to shmdt and mmap depend on passing a void*. In the obsolete XPG4 version of Unix (roughly POSIX.2a-1992), these functions indeed took a void* argument. In all later versions of standard Unix, these functions take a char* argument. Portable code therefore cannot depend on passing a void*, but can depend on passing a char* to these functions.

The offending code should be changed either to pass a char* argument, or the argument should be cast to char* at the point of the call."	Bugs	closed	To Be Determined	interprocess	Boost 1.44.0	Problem	invalid
