NAME

       munge_enum_is_valid,  munge_enum_int_to_str,  munge_enum_str_to_int  -  MUNGE  enumeration
       functions

SYNOPSIS

       #include <munge.h>

       int munge_enum_is_valid (munge_enum_t type, int val);

       const char * munge_enum_int_to_str (munge_enum_t type, int val);

       int munge_enum_str_to_int (munge_enum_t type, const char *str);

       cc `pkg-config --cflags --libs munge` -o foo foo.c

DESCRIPTION

       The munge_enum_is_valid() function checks  if  the  given  value  val  is  a  valid  MUNGE
       enumeration  of  the  specified  type  type  in  the  software  configuration as currently
       compiled.  Some enumerations correspond to options that can only be  enabled  at  compile-
       time.

       The  munge_enum_int_to_str()  function converts the MUNGE enumeration val of the specified
       type type into a text string.

       The munge_enum_str_to_int() function converts the NUL-terminated  case-insensitive  string
       str into the corresponding MUNGE enumeration of the specified type type.

RETURN VALUE

       The  munge_enum_is_valid()  function  returns  non-zero  if the given value val is a valid
       enumeration.

       The munge_enum_int_to_str() function returns a NUL-terminated  constant  text  string,  or
       NULL on error; this string should not be freed or modified by the caller.

       The  munge_enum_str_to_int() function returns a MUNGE enumeration on success (i.e., >= 0),
       or -1 on error.

ENUM TYPES

       The following enumeration types can be specified.

       MUNGE_ENUM_CIPHER
              Specify enumerations for the available cipher types.

       MUNGE_ENUM_MAC
              Specify enumerations for the available MAC types.

       MUNGE_ENUM_ZIP
              Specify enumerations for the available compression types.

ERRORS

       Refer to munge(3) for a complete list of errors.

EXAMPLE

       The following example program illustrates how a list of  available  cipher  types  can  be
       queried.

       #include <stdio.h>                      /* for printf() */
       #include <stdlib.h>                     /* for exit() */
       #include <munge.h>

       int
       main (int argc, char *argv[])
       {
           int           i;
           const char   *p;
           munge_enum_t  t = MUNGE_ENUM_CIPHER;

           for (i = 0; (p = munge_enum_int_to_str (t, i)) != NULL; i++) {
               if (munge_enum_is_valid (t, i)) {
                   printf ("%2d = %s\n", i, p);
               }
           }
           exit (0);
       }
