These prototypes are: int capget(cap_user_header_t header, cap_user_data_t data); int capset(cap_user_header_t header, const cap_user_data_t data); Further, libcap provides a set-up function, void cap_set_syscall( long int (*new_syscall)(long int, long int, long int, long int), long int (*new_syscall6)(long int, long int, long int, long int, long int, long int, long int)); which can be used to redirect its use of the capset() and other system calls that write kernel managed state. This is especially useful when supporting POSIX semantics for security state. When a program is linked against libpsx(3) as described in that man page, this function is used to connect libcap to POSIX semantics system calls.

This site is devoted to announcing new versions of libcap (both C and Go implementations), and sharing information about using Linux Capabilities -- an alternative to the superuser model of privilege under Linux. Resources: Release notes for libcap, libpsx and Go packages cap and psx. You can read
