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.
