# pmunloadnamespace(3)

unload a local performance metrics name space for an application

Part of [pmUnloadNameSpace(3)](/pmUnloadNameSpace/3.md).

## NAME

**pmUnloadNameSpace** - unload a local performance metrics name space for an application

## C SYNOPSIS

**#include \<pcp/pmapi.h\>**

**void pmUnloadNameSpace(void);**

**cc ... -lpcp**

## DESCRIPTION

If one has previously loaded a local Name Space using [**pmLoadNameSpace**(3)](/pmLoadNameSpace/3.md) or [**pmLoadASCIINameSpace**(3)](/pmLoadASCIINameSpace/3.md), then calling [**pmUnloadNameSpace**(3)](/pmUnloadNameSpace/3.md) will free up the memory associated with the Name Space and force all subsequent PMNS routine calls to use the distributed PMNS. If [**pmUnloadNameSpace**(3)](/pmUnloadNameSpace/3.md) is called before calling [**pmLoadNameSpace**(3)](/pmLoadNameSpace/3.md) or [**pmLoadASCIINameSpace**(3)](/pmLoadASCIINameSpace/3.md), then it will effectively do nothing.
