Re: How do you create a file descriptor from memory (oposite of mmap)?

[Marat BN <maratbn@xxxxxxxxx>]

Did some more digging around, and came across the fmemopen function, that accepts a pointer to a local memory buffer, and returns a FILE * pointer to the buffer as if it was a file.

 

Found it here:

Hi,

 

This is regarding message your "How do you create a file descriptor from memory (oposite of mmap)?" that you posted back in 2003.  I read it here: http://mail.nl.linux.org/kernelnewbies/2003-04/msg00075.html

 

It looks like you had one reply on this, and the replier stated that there is no way to have a file descriptor to a memory buffer without creating a file.  It would be really nifty to have a file descriptor to a memory buffer without having to involve the filesystem.  Have you been able to find any other solution to this problem since 2003?

 

Thanks,

Marat
