SYNOPSIS

12       #include <munge.h>
13
14       int munge_enum_is_valid (munge_enum_t type, int val);
15
16       const char * munge_enum_int_to_str (munge_enum_t type, int val);
17
18       int munge_enum_str_to_int (munge_enum_t type, const char *str);

DESCRIPTION

24       The munge_enum_is_valid() function checks if the given value val  is  a
25       valid MUNGE enumeration of the specified type type in the software con‐
26       figuration as currently compiled.  Some enumerations correspond to  op‐
27       tions that can only be enabled at compile-time.
28
29       The munge_enum_int_to_str() function converts the MUNGE enumeration val
30       of the specified type type into a text string.
31
32       The munge_enum_str_to_int() function converts the NUL-terminated  case-
33       insensitive  string str into the corresponding MUNGE enumeration of the
34       specified type type.

36

RETURN VALUE

38       The munge_enum_is_valid() function returns non-zero if the given  value
39       val is a valid enumeration.
40
41       The  munge_enum_int_to_str() function returns a NUL-terminated constant
42       text string, or NULL on error; this string should not be freed or modi‐
43       fied by the caller.
44
45       The  munge_enum_str_to_int()  function  returns  a MUNGE enumeration on
46       success (i.e., >= 0), or -1 on error.

EXAMPLE

67       The following example program illustrates how a list of  available  ci‐
68       pher types can be queried.
69
70       #include <stdio.h>                      /* for printf() */
71       #include <stdlib.h>                     /* for exit() */
72       #include <munge.h>
73
74       int
75       main (int argc, char *argv[])
76       {
77           int           i;
78           const char   *p;
79           munge_enum_t  t = MUNGE_ENUM_CIPHER;
80
81           for (i = 0; (p = munge_enum_int_to_str (t, i)) != NULL; i++) {
82               if (munge_enum_is_valid (t, i)) {
83                   printf ("%2d = %s\n", i, p);
84               }
85           }
86           exit (0);
