man munge_enum_int_to_str (3): MUNGE enumeration functions

Other Alias

munge_enum_is_valid, munge_enum_str_to_int

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);
}
