SELinux Network Ports Management API

## NAME

semanage\_port - SELinux Network Ports Management API

## SYNOPSIS

**#include \<semanage/port\_record.h\>**\
 **#include \<semanage/ports\_policy.h\>**\
 **#include \<semanage/ports\_local.h\>**

This object contains properties associated with a range of network ports.

For details on a specific function, see its manual page.

## Record API Overview

**semanage\_port\_create**(3)**-**\
 create a port range

**semanage\_port\_free**(3)**-**\
 release resources for this port range

**semanage\_port\_key\_create**(3)**-**\
 create a key, which can be used to identify a port range

**semanage\_port\_key\_free**(3)**-**\
 release resources for this port range key

**semanage\_port\_key\_extract**(3)**-**\
 create a key matching this port range

**semanage\_port\_clone**(3)**-**\
 create an identical port range (deep-copy clone)

**semanage\_port\_compare**(3)**-**\
 compare this port range to the provided key

**semanage\_port\_compare2**(3)**-**\
 compare this port range to another

## Properties API Overview

**semanage\_port\_get\_proto**(3)**-**\
 return the protocol for this port range

**semanage\_port\_get\_proto\_str**(3)**-**\
 return a string representation of the given port protocol

**semanage\_port\_set\_proto**(3)**-**\
 set the protocol for this port range

**semanage\_port\_get\_low**(3)**-**\
 return the low port number for this port range

**semanage\_port\_get\_high**(3)**-**\
 return the high port number for this port range

**semanage\_port\_set\_port**(3)**-**\
 set the port number (same low and high) for this port range

**semanage\_port\_set\_range**(3)**-**\
 set the low and high port number for this port range

**semanage\_port\_get\_con**(3)**-**\
 return the SELinux context for this port range

**semanage\_port\_set\_con**(3)**-**\
 set the SELinux context for this port range
