| 20 | .\" ////////////////////////////////////////////////////////////////////////// |
| 21 | .P |
| 22 | Releases the seccomp filter in |
| 23 | .I ctx |
| 24 | which was first initialized by |
| 25 | .BR seccomp_init (3) |
| 26 | or |
| 27 | .BR seccomp_reset (3) |
| 28 | and frees any memory associated with the given seccomp filter context. |
| 29 | Any seccomp filters loaded into the kernel are not affected. |

| 56 | .SH NOTES |
| 57 | .\" ////////////////////////////////////////////////////////////////////////// |
| 58 | .P |
| 59 | While the seccomp filter can be generated independent of the kernel, kernel |
| 60 | support is required to load and enforce the seccomp filter generated by |
| 61 | libseccomp. |
