nExtMem() and Os()

Post by sambomb »

nExtMem() isn't returning the correct amount of memory and the OS() function doensn't work in windows 8 or above, returning windows NT instead

Is this related to my FWH / xHarbour version?

Compiler version: xHarbour build 1.2.1 Intl. (SimpLex) (Rev. 6715)
FiveWin Version: FWHX 10.6

Gostaria de utilizar a função OS pois ela já retorna o modelo do SO também pois alguns modelos geram incompatibilidade, como o windows 7 starter...

a nExtMem está retornando valores inválidos, minha máquina é um Windows 7 que tem 4 GB ( utilizável 3,24 ) sendo que reconhece apenas 2 GB em uma máquina com Windows 8.1, reconhece como negativo!
E a função Os() é nativa do xHarbour, mas parece que não foi atualizada, ela retorna todas as informações que eu preciso, queria saber não apenas a versão do Windows, mas também o tipo de licença dele como disse acima, mas muito obrigado, estou desenvolvendo uma rotina que poderei aproveitar trechos dessa TSystem

Windows 8.1, reconhece como negativo?

Você incorporou o GETSYSIN.PRG modificado por mim, logo acima?

Você tem a função Os() do xHarbour? Talvez o Marcelo Lombardo tenha uma mais recente.

Seria algo assim?

Don't know about xHarbour, but probably this is sth related to the numeric type used by nExtMem() an xHabour's integers. Using a 4 byte UNSIGNED LONG we can represent integers from 0 to 256^4-1, or 4,294,967,295, or SIGNED, ranging from -2,147,483,647 TO 2,147,483,648. I think the function is working fine, but returning an UNSIGNED LONG that xHarbour is handling as signed, so that's why you ar getting negative results. A quick temporary patch can be that, in case of a negative result, it should be substracted from 256^4-1, wich will result in your case to 3840 Mb, that is your claimd free mem.
Obvously, this patch will fail in PC with more than 4 GB, as probably will do anything in 32 bits with results expresing byte counts that a 4 byte LONG won't be able to represent.
