# seccomp\_release(3)

Release the seccomp filter state

## NAME

seccomp\_release - Release the seccomp filter state

## SYNOPSIS

```
#include <seccomp.h>

typedef void * scmp_filter_ctx;

void seccomp_release(scmp_filter_ctx ctx);

Link with -lseccomp.
```

## DESCRIPTION

Releases the seccomp filter in *ctx* which was first initialized by [**seccomp\_init**(3)](/seccomp_init/3.md) or [**seccomp\_reset**(3)](/seccomp_reset/3.md) and frees any memory associated with the given seccomp filter context. Any seccomp filters loaded into the kernel are not affected.

## RETURN VALUE

Does not return a value.

## EXAMPLES

```
#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;
	/* ... */
	seccomp_release(ctx);
	return 0;
}
```

## 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.
