I am writing a shared library in Linux (but compatible with other UNIXes) and I want to allow multiple instances to share a piece of memory -- 1 byte is enough. What's the "best" way to do this? I want to optimize for speed and portability.
Obviously, I'll have to worry about mutual exclusion. (0 Replies)

SYSFS(2) Linux Programmer's Manual SYSFS(2)
NAME
sysfs - get filesystem type information
SYNOPSIS
int sysfs(int option, const char *fsname);
int sysfs(int option, unsigned int fs_index, char *buf);
int sysfs(int option);
DESCRIPTION
Note: if you are looking for information about the sysfs filesystem that is normally mounted at /sys, see sysfs(5).
The (obsolete) sysfs() system call returns information about the filesystem types currently present in the kernel. The specific form of
the sysfs() call and the information returned depends on the option in effect:
1 Translate the filesystem identifier string fsname into a filesystem type index.
2 Translate the filesystem type index fs_index into a null-terminated filesystem identifier string. This string will be written to the
buffer pointed to by buf. Make sure that buf has enough space to accept the string.
3 Return the total number of filesystem types currently present in the kernel.
The numbering of the filesystem type indexes begins with zero.
RETURN VALUE
On success, sysfs() returns the filesystem index for option 1, zero for option 2, and the number of currently configured filesystems for
option 3. On error, -1 is returned, and errno is set appropriately.
ERRORS
EFAULT Either fsname or buf is outside your accessible address space.
EINVAL fsname is not a valid filesystem type identifier; fs_index is out-of-bounds; option is invalid.
CONFORMING TO
SVr4.
NOTES
This System-V derived system call is obsolete; don't use it. On systems with /proc, the same information can be obtained via
/proc/filesystems; use that interface instead.
BUGS
There is no libc or glibc support. There is no way to guess how large buf should be.
