PMSETPROGNAME(3)         Library Functions Manual        PMSETPROGNAME(3)

NAME         top

       pmSetProgname, pmGetProgname - application name services

C SYNOPSIS         top

       #include <pcp/pmapi.h>

       void pmSetProgname(const char *program);
       char *pmGetProgname(void);

       cc ... -lpcp

DESCRIPTION         top

       Within  the Performance Co-Pilot (PCP) run-time libraries the name
       of a running application is maintained to be used in error and di‐
       agnostic messages.

       The default application name is pcp.

       pmSetProgname may be used to set the application name  to  program
       after  stripping  any  leading  components  that  begin  with  the
       filesystem path name separator (``/'' for Unix-like systems).

       It is the callers responsibility to ensure the memory  pointed  to
       by  program  remains  available  for  the life of the application.
       Typically, the value passed as program for a C  program  would  be
       argv[0].   If program is NULL, the default application name is re‐
       stored.

       pmGetProgname may be used to return the current application name.
