Library Synopsis Description Return Values See Also History Bugs
.In paths.h const char * getbootfile void
The getbootfile function retrieves the full pathname of the file from which the current kernel was loaded, and returns a static pointer to the name. A read/write interface to this information is available via the sysctl(3) MIB variable "kern.bootfile".
If the call succeeds a string giving the pathname is returned. If it fails, a null pointer is returned and an error code is placed in the global location errno.
