NAME

     pseudofs -- pseudo file system construction kit

SYNOPSIS

     #include <fs/pseudofs/pseudofs.h>

DESCRIPTION

     The pseudofs module offers an abstract API for pseudo-file systems such as procfs(5) and linprocfs(5).  It takes care of all the hairy bits
     like interfacing with the VFS system, enforcing access control, keeping track of file numbers, and cloning files and directories that are
     process-specific.	The consumer module, i.e., the module that implements the actual guts of the file system, needs only provide the directory
     structure (represented by a collection of structures declared and initialized by macros provided by pseudofs) and callbacks that report file
     attributes or write the actual file contents into sbufs.

SEE ALSO

     linprocfs(5), linsysfs(5), procfs(5), sbuf(9), vnode(9)

HISTORY

     The pseudofs module appeared in FreeBSD 5.0.

NAME

     kld_isloaded, kld_load -- kld utility functions

LIBRARY

     System Utilities Library (libutil, -lutil)

SYNOPSIS

     #include <libutil.h>

     int
     kld_isloaded(const char *name);

     int
     kld_load(const char *name);

DESCRIPTION

     These functions facilitate loading kernel modules from userland applications.

     The kld_isloaded() function takes a name and returns a non-zero value if a module of that name is currently loaded.  The name can be either
     the name of a module file (cpufreq.ko), the same name without the .ko extension (cpufreq), or the name of a module contained within that file
     (cpu/ichss).  Only the latter will return correct results if the module is compiled into the kernel.

     The kld_load() function is a simple wrapper around the kldload(2) function.  It returns zero if and only if the corresponding kldload() call
     succeeded or returned EEXIST (signifying that the requested module was already loaded).

SEE ALSO

     kldfirstmod(2), kldload(2), kldnext(2), kldstat(2), modfnext(2), modstat(2), kld(4)

HISTORY

     The kld_isloaded() and kld_load() functions first appeared in FreeBSD 6.3.
