# capng\_fill(3)

fill chosen capabilities set

## NAME

capng\_fill - fill chosen capabilities set

## SYNOPSIS

**#include \<cap-ng.h\>**

void capng\_fill(capng\_select\_t set);

## DESCRIPTION

capng\_fill sets all bits to a 1 in the selected POSIX capabilities set. The options are CAPNG\_SELECT\_CAPS for the traditional capabilities, CAPNG\_SELECT\_BOUNDS for the bounding set, CAPNG\_SELECT\_BOTH if filling both is desired, CAPNG\_SELECT\_AMBIENT if only operating on the ambient capabilities, or CAPNG\_SELECT\_ALL if filling all is desired.

## RETURN VALUE

None.

## NOTES

During capng\_apply, bits in the bounding set can only be dropped. You cannot set them.
