PMLOADASCIINAMESPACE(3) 				     Library Functions Manual					   PMLOADASCIINAMESPACE(3)

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) 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.

       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 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	configura-
       tion file, as described in pcp.conf(5).	Values for these variables may be obtained programmatically 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.
