NAME         top

       seccomp_release - Release the seccomp filter state

SYNOPSIS         top

       #include <seccomp.h>

       typedef void * scmp_filter_ctx;

       void seccomp_release(scmp_filter_ctx ctx);

       Link with -lseccomp.

DESCRIPTION         top

       Releases the seccomp filter in ctx which was first initialized by
       seccomp_init(3) or seccomp_reset(3) and frees any memory associated
       with the given seccomp filter context.  Any seccomp filters loaded
       into the kernel are not affected.

RETURN VALUE         top

       Does not return a value.

EXAMPLES         top

       #include <seccomp.h>

       int main(int argc, char *argv[])
            int rc;
            scmp_filter_ctx ctx;

            ctx = seccomp_init(SCMP_ACT_KILL);
            if (ctx == NULL)
                 return -1;

            /* ... */

            return 0;

NOTES         top

       While the seccomp filter can be generated independent of the kernel,
       kernel support is required to load and enforce the seccomp filter
       generated by libseccomp.

       The libseccomp project site, with more information and the source
       code repository, can be found at  This tool, as well as the
       libseccomp library, is currently under development, please report any
       bugs at the project site or directly to the author.
