Dear all,

im porting a WIN APP to LINUX, and face some problems that r hard for
me to solve, could u dear guys give me some hands?


i'd like to reimplement the following funcs or replace them with other
ways , but i have no idea how to !!


1. HLOCAL LocalAlloc( UINT uFlags, SIZE_T uBytes)

MSDN: The LocalAlloc function allocates the specified number of bytes
from the heap. Windows memory management does not provide a separate
local heap and global heap.

Also:	LocalFree



2. HGLOBAL GlobalAlloc( UINT uFlags, SIZE_T dwBytes)

MSDN: The GlobalAlloc function allocates the specified number of bytes
from the heap. Windows memory management does not provide a separate
local heap and global heap.

Also:	GlobalFree, GlobalLock, GlobalUnlock



3. LPVOID VirtualAlloc(LPVOID lpAddress, SIZE_T dwSize,DWORD
flAllocationType, DWORD flProtect )

MSDN: The VirtualAlloc function reserves or commits a region of pages
in the virtual address space of the calling process. Memory allocated
by this function is automatically initialized to zero, unless MEM_RESET
is specified.

Also:	VirtualFree, VirtualLock, VirtualUnlock



4. BOOL AnsiToOem( LPCSTR lpszSrc,LPSTR lpszDst)

MSDN: Converts all the characters in this CStringT object from the ANSI
character set to the OEM character set.

Also:	OemToAnsi, AnsiToOemBuff


thx!

hi Rullg=E5rd,

4=2E OemToAnsi

i think u r right, using iconv_open(), iconv(), and iconv_close()

and i used "iconv --list" to get CHAR SET, i DON'T KNOW which 2 char
sets i should choose.

could anyone tell me whats the corresponding char set name of OEM and
ANSI ??

thx!

ANSI have standardised quite a large number of character sets, so
without any context, the question has no meaning.  OEM is apparently a
MS-ism for IBM DOS codepages, not a particular charset, and ANSI is
WinCP1252 (!):

Basically, the MS nomenclature is meaningless garbage.
