# sysdecode\_cap\_rights(3)

output list of capability rights

## NAME

**sysdecode\_cap\_rights** – output list of capability rights

## LIBRARY

library “libsysdecode”

## SYNOPSIS

**#include \<sysdecode.h\>**

*void*\

**sysdecode\_cap\_rights**(*FILE \*fp*, *cap\_rights\_t \*rightsp*);

## DESCRIPTION

The **sysdecode\_cap\_rights**() function outputs a comma-separated list of capability rights at *rightsp* to the stream *fp*.

Note that some capability rights are supersets of others; for example, CAP\_PREAD is the union of CAP\_READ and CAP\_SEEK. **sysdecode\_cap\_rights**() emits a minimal list of rights whose union is equal to *\*rightsp*. For example, if both CAP\_READ and CAP\_SEEK are set in *\*rightsp*, then **sysdecode\_cap\_rights**() will include only CAP\_PREAD in the output list.
