SH_DENY* equivalent in Solaris

Question

Solaris equivalent to fcntl.h and share.h

I am porting a big C++ project from Windows/VS to Solaris/Eclipse/gcc. The Windows code uses _SH_DENYNO etc which are in a Microsoft file share.h. The same file on the Sun at /usr/include/sys does not contain these, nor does any other I can find.

I suppose they have another name in Solaris. Can someone tell me where to find their equivalent? The windows versions have these values:

 #define _SH_DENYRW      0x10    /* deny read/write mode */
 #define _SH_DENYWR      0x20    /* deny write mode */
 #define _SH_DENYRD      0x30    /* deny read mode */
 #define _SH_DENYNO      0x40    /* deny none mode */
 #define _SH_SECURE      0x80    /* secure mode */

Do the Solaris versions have the same values?

(Sorry about the big font, it insisted)

I think solaris, like other unix, is always _SH_DENYNO. You need explicit locking of files, try lockf or fcntl.
