* SystemFileDescriptor is returning current Limit & max system limit for file descriptor (open file or I/O resource) currently set in the system
|
|
* This function return the current setting (current number of file descriptor and the max value) if the newValue given is zero
|
|
* Otherwise if the newValue is more than the current system limit, try to change the current limit in the system for this process only
|
|
*
|
|
* For Windows build, please follow this note :
|
|
* 1) install package gcc-multilib gcc-mingw-w64 to build C source with GCC
|
|
* you will having this binaries
|
|
* - i686-w64-mingw32* for 32-bit Windows;
|
|
* - x86_64-w64-mingw32* for 64-bit Windows.
|
|
* locate you binaries gcc mingw path and note it:
|
|
* - win32 : updatedb && locate i686-w64-mingw32-gcc
|
|
* - win64 : updatedb && locate x86_64-w64-mingw32-gcc
|
|
* 2) if you have an error in the build, or if the .o object file is not present in golib/njg-ioutils/maxstdio/, run this step
|
|
* - go to golib/njg-ioutils/maxstdio folder
|
|
* - gcc -c maxstdio.c
|
|
* 3) for Win32 use this env var in prefix of your go build command (recommend to use -a flag) :
|
|
* CC=/usr/bin/i686-w64-mingw32-gcc CGO_ENABLED=1 GOOS=windows GOARCH=amd64 go build -a -v ...
|
|
* 4) for win64 use this env var in prefix of your go build command (recommend to use -a flag) :
|
|
* CC=/usr/bin/x86_64-w64-mingw32-gcc CGO_ENABLED=1 GOOS=windows GOARCH=amd64 go build -a -v ...
|
|
*
|
|
* Normally no problem will be result in the build
