O_DIRECT giving error while compiling the source code

HI QNX,

I am compiling one of the source code which having OPEN( ) function call having O_DIRECT to open the file.

But i am getting error while compiling that O_DIRECT is  not declared.

Is there any alternate to use to open the file which does same functionality as O_DIRECT.

Thanks in advance 

Thanks & Regards
Janardhan Reddy

Re: O_DIRECT giving error while compiling the source code

I think O_DIRECT is not supported under QNX. Since it is a performance optimization, you could simply do something like

#ifnef O_DIRECT
#define O_DIRECT   0
#endif

Regards,
Albrecht
