munge_enum

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 ... -lmunge
 

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);
 }
