       pmLoadASCIINameSpace - establish a local PMNS for an application

       #include <pcp/pmapi.h>

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

       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.

       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.

       $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 config-
       uration	file,  as  described  in pcp.conf(5).  Values for these variables may be obtained
       programmatically using the pmGetConfig(3) function.

       PMAPI(3), pmGetConfig(3), pmLoadNameSpace(3), pmTrimNameSpace(3), pcp.conf(5),  pcp.env(5)
       and pmns(5).

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


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


	      Syntax error in an ASCII format PMNS.
