setrlimit64()

[Tony LeBlanc]

I am compiling some code that uses setrlimit64() to set a filesize limit greater than 2GB but the limit is not being set.

Can someone please explain??

The system is running in 64-bit mode.

Tony,

Does the location of the file accept files greater than 2GB (largefiles)?

First of all, are you checking the result of your setrlimit64 call? If it is non-zero, you need to check errno. You may not have permission to increase this limit. Also, are largefiles enabled in the filesystem?

[Tony LeBlanc]

The return value of the call is 0. The file system is an nfs mount wich can handle large files.

I don't think the filesystem should matter here, I am just trying to set a limit, not actualy create a large file.

Here is my compile string:

cc -g -D_LARGEFILE64_SOURCE

Okay, I assume that you are doing a setrlimit() followed by a getrlimit() to check the values. Bear in mind that the setrlimit() system call using RLIMIT_FSIZE only applies to UNIX 95 code; I think that is also true of the setrlimit64() system call.
