NAME         top

       seccomp_version - Query the libseccomp version information

SYNOPSIS         top

       #include <seccomp.h>

       struct scmp_version {
            unsigned int major;
            unsigned int minor;
            unsigned int micro;

       const struct scmp_version *seccomp_version(void);

       Link with -lseccomp.

DESCRIPTION         top

       The seccomp_version() and seccomp_reset() functions return a pointer
       to a scmp_version struct which contains the version information of
       the currently loaded libseccomp library.  This function can be used
       by applications that need to verify that they are linked to a
       specific libseccomp version at runtime.

       The caller should not attempt to free the returned scmp_version
       struct when finished.

RETURN VALUE         top

       The seccomp_version() function returns a pointer to a scmp_version
       structure on success, NULL on failure.  The caller should not attempt
       to free the returned structure.

EXAMPLES         top

       #include <seccomp.h>

       int main(int argc, char *argv[])
            const struct scmp_version *ver;

            ver = seccomp_version();
            if (ver == NULL)
                 goto err;

            /* ... */

            return 0;

            return -1;

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.
