NAME

       seccomp_version - Query the libseccomp version information

SYNOPSIS

       #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

       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

       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

       #include <seccomp.h>

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

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

            /* ... */

            return 0;

       err:
            return -1;
       }

NOTES

       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
       https://github.com/seccomp/libseccomp.  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.
