NAME

6       explain_program_name - manipulate the program name
7

SYNOPSIS

9       #include <libexplain/libexplain.h>
10       const char *explain_program_name_get(void);
11       void explain_program_name_set(const char *name);
12       void explain_program_name_assemble(int yesno);
13

DESCRIPTION

15       These functions may be used to manipulate libexplain's idea of the com‐
16       mand name of the current process, and  whether  or  not  that  name  is
17       included in error messages.
18
19   explain_program_name_get
20       const char *explain_program_name_get(void);
21
22       The explain_program_name_get function may be used to obtain the command
23       name of the calling process.  Depending on how capable /proc is on your
24       system,  or,  failing that, how capable lsof(1) is on your system, this
25       may or may not produce a sensible result.  It works well on Linux.
26
27       Returns:
28               pointer to string containing the command name (no  slashes)  of
29               the calling process.
30
31   explain_program_name_set
32       void explain_program_name_set(const char *name);
33
34       The explain_program_name_set function may be used to set the libexplain
35       libraries' idea of the command name of the calling process, setting the
36       string  to  be  returned  by  the explain_program_name_get(3) function.
37       This overrides the automatic behavior, which can be quite desirable  in
38       commands  that can be invoked with more than one name, e.g. if they are
39       a hard link synonym.
40
41       This also sets the option to include the program name  in  all  of  the
42       error messages issued by the explain_*_or_die(3) functions.
43
44       name    The  name  of  the  calling process.  Only the basename will be
45               used if a path containing slashes is given.
46
47   explain_program_name_assemble
48       void explain_program_name_assemble(int yesno);
49
50       The explain_program_name_assemble function is used to  control  whether
51       or  not the name of the calling process is to be included in error mes‐
52       sages issued by the explain_*_or_die(3) functions.  If  not  explicitly
53       set,  is  controlled  by  the  EXPLAIN_OPTIONS environment variable, or
54       defaults to true if not set there either.
55
56       yesno   non‐zero (true) to have program name included, zero (false)  to
57               have program name excluded.
