munge_enum3

Usage

#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

Overview

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 null-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 null-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.

Errors

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

Examples

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

#include <stdio.h>
#include <stdlib.h>
#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 (EXIT_SUCCESS);
