fcntl call on win95

[Ian Collins]

I have a routine that write locks a file. The essential code is,

#include <fcntl.h>
auto struct flock lck;
auto int flc;
auto int filedesc;

filedesc = open(filename, O_RDWR|O_CREAT, 0666);
lck.l_type = F_WRLCK;
lck.l_start = 0;
lck.l_whence = 0;
lck.l_len = 0;
flc = fcntl(fildesc, F_SETLK, &lck);

The fcntl provides a write lock on Windows NT fine (on both FAT and
NTFS) filesystems, but fails (flc == -1) on Windows 95.
Can anyone help me on this?

Many Regards,
Ian Collins
