explain_program_name(3)     Library Functions Manual	 explain_program_name(3)

NAME
     explain_program_name - manipulate the program name

SYNOPSIS
     #include <libexplain/libexplain.h>
     const char *explain_program_name_get(void);
     void explain_program_name_set(const char *name);
     void explain_program_name_assemble(int yesno);

DESCRIPTION
     These  functions may be used to manipulate libexplain's idea of the command
     name of the current process, and whether or not that name	is  included  in
     error messages.

   explain_program_name_get
     const char *explain_program_name_get(void);

     The  explain_program_name_get  function  may  be used to obtain the command
     name of the calling process.  Depending on how capable  /proc  is	on  your
     system,  or,  failing that, how capable lsof(1) is on your system, this may
     or may not produce a sensible result.  It works well on Linux.

     Returns:
	     pointer to string containing the command name (no slashes)  of  the
	     calling process.

   explain_program_name_set
     void explain_program_name_set(const char *name);

     The explain_program_name_set function may be used to set the libexplain li-
     braries'  idea  of  the  command  name  of the calling process, setting the
     string to be returned by the  explain_program_name_get(3)	function.   This
     overrides	the automatic behavior, which can be quite desirable in commands
     that can be invoked with more than one name, e.g. if they are a  hard  link
     synonym.

     This  also  sets the option to include the program name in all of the error
     messages issued by the explain_*_or_die(3) functions.

     name    The name of the calling process.  Only the basename will be used if
	     a path containing slashes is given.

   explain_program_name_assemble
     void explain_program_name_assemble(int yesno);

     The explain_program_name_assemble function is used to  control  whether  or
     not the name of the calling process is to be included in error messages is-
     sued  by the explain_*_or_die(3) functions.  If not explicitly set, is con-
     trolled by the EXPLAIN_OPTIONS environment variable, or defaults to true if
     not set there either.

     yesno   non-zero (true) to have program name included, zero (false) to have
	     program name excluded.
