NAME

       pmLoadASCIINameSpace - establish a local PMNS for an application

C SYNOPSIS

       #include <pcp/pmapi.h>

       int pmLoadASCIINameSpace(const char *filename, int dupok);

       cc ... -lpcp

DESCRIPTION

       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.

       pmLoadASCIINameSpace is a variant of pmLoadNameSpace(3) which will only process  an  ASCII
       format  PMNS, and 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.

       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; although since the default local PMNS will exist in a
       binary format, pmLoadNameSpace(3) would be the more efficient routine to use.

       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 returns zero on success.

FILES

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

PCP ENVIRONMENT

       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(4).   Values  for  these  variables  may  be
       obtained programatically using the pmGetConfig(3) function.

DIAGNOSTICS

       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.
