Hi,

I am having trouble with a munmap call failing with an invalid argument.
munmap seems to have 3 error conditions, I can eliminate 2 of those (len
<=0, and mem block size not divisible by page size), which leave me with
address + size outside process memory space. Is this a common problem?
Following is some debug output:

Just Mmaped 20480 which is now at address 1A440000

About to UnMapp 20480 at 1A440000

The code works fine under Linux but falls over with munmap: Invalid Argument
under cygwin gcc.

Any help appreciated.

Regards,
Shane
