| 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. | |

| 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. | |
| 62 | .P | |
| 63 | The libseccomp project site, with more information and the source code | |
| 64 | repository, can be found at https://github.com/seccomp/libseccomp. This tool, | |
| 65 | as well as the libseccomp library, is currently under development, please | |
