NAME
capng_get_caps_fd - read file-based capabilities from extended
attributes
SYNOPSIS
#include <cap-ng.h>
int capng_get_caps_fd(int fd);
DESCRIPTION
This function will read the file based capabilities stored in extended
attributes of the file that the descriptor was opened against. The
bounding set is not included in file based capabilities operations.
Note that this function will only work if compiled on a kernel that
supports file based capabilities such as 2.6.26 and later. If the
"magic" bit is set, then all effect capability bits are set. Otherwise
the bits are cleared.
RETURN VALUE
This returns 0 on success and -1 on failure.
