pmLoadASCIINameSpace - establish a local PMNS for an application

#include<pcp/pmapi.h>intpmLoadASCIINameSpace(constchar*filename,intdupok);cc...-lpcp

       If  the  application  wants  to  force  using  a local Performance Metrics Name Space (PMNS) instead of a
       distributed PMNS then it must load the PMNS using pmLoadASCIINameSpace  or  pmLoadNameSpace(3).   If  the
       application wants to use a distributed PMNS, then it should NOT make a call to load the PMNS explicitly.

       Most  applications  using a Performance Metrics Application Programming Interface (PMAPI) context (of any
       type,  so  PM_CONTEXT_HOST  or  PM_CONTEXT_ARCHIVE  or  PM_CONTEXT_LOCAL)  should  not   need   to   call
       pmLoadASCIINameSpace.

       The  filename  argument designates the PMNS of interest.  For applications not requiring a tailored PMNS,
       the special value PM_NS_DEFAULT may be used for filename, to force the default local PMNS to be loaded.

       The default local PMNS is found in  the  file  $PCP_VAR_DIR/pmns/root  unless  the  environment  variable
       PMNS_DEFAULT  is  set,  in  which case the value is assumed to be the pathname to the file containing the
       default local PMNS.

       pmLoadASCIINameSpace is a variant of pmLoadNameSpace(3) in which  the  dupok  argument  may  be  used  to
       control  the  handling  of  multiple  names  in the PMNS that may be associated with a single Performance
       Metric Identifier (PMID).  A value of 0 disallows duplicates, any other value allows duplicates  and  the
       latter is the default behaviour of pmLoadNameSpace(3) as of Version 3.10.3 of PCP.

       The  other  difference  is  that when pmLoadASCIINameSpace is used and filename is not PM_NS_DEFAULT, the
       PMNS file will always be preprocessed with pmcpp(1) as described in PMNS(5).  This  allows  a  PMNS  file
       that  contains  C-style  comments, preprocessor directives or macros to be processed correctly before the
       PMNS is parsed.

       pmLoadASCIINameSpace returns zero on success.

       Syntax and other errors in the parsing of the PMNS are reported on stderr with  a  message  of  the  form
       ``Error Parsing ASCII PMNS: ...''.

       PM_ERR_DUPPMNS

              It  is  an  error to try to load more than one PMNS, or to call either pmLoadASCIINameSpace and/or
              pmLoadNameSpace(3) more than once.

       PM_ERR_PMNS

              Syntax error in an ASCII format PMNS.

$PCP_VAR_DIR/pmns/root   the default local PMNS, when the environment variable PMNS_DEFAULT is unset

       Environment variables with the prefix PCP_ are used to parameterize the file and directory names used  by
       PCP.   On  each  installation, the file /etc/pcp.conf contains the local values for these variables.  The
       $PCP_CONF variable may be used to specify an alternative configuration file, as described in pcp.conf(5).
       Values for these variables may be obtained programmatically using the pmGetConfig(3) function.
