library :: QString to LPSTR

[josecarlosmissias]

Hello everyone,
I'm loading a library in "C" and its functions require parameters of type LPSTR.
Do you have any way to convert QString to LPSTR?

Grateful.

Look at the the LPSTR difintion, and you will see its typedef CHAR*...

right, how do I convert QString to char *, eg:
//--------------------
typedef int (* CaptTxtDllECF) (int type, char * faixai, faixaf char *, char * path, int show char * str);

....
//------------------
QString pathToSave = "c:\\tmp\\lx.txt";
status = captTxtDllECF (_LX, "", "", path, 1, "serial");

error:

C: / workspace / captureW /. / Main.cpp: 227: error: 'int (int, char *, char *, char *, int, char *)': can not convert parameter 4 from 'QString' to 'char * '

Well, QString has a toLocal8Bit method, and QByteArray has a method constData to return a const char *. Or you use Data instead to remove the const'ness. Its better to use the former unless you need to modify the string however.
