    <p>I'm building a validation function for a particular enumeration data type. The validation function returns 0 (false) or 1 (true) if string passed is valid. At the same time, if the string is valid, then the enumeration subType is then populated with the correct entry. </p> <p>As the code is, it correctly populates subType in the function. I print the entry to the screen to check. But when I return to the main (see below), I get a garbage value (sometimes '11871397') when I print the string. </p> <p>I've even tried this with or without declaring subType as const. I have a number of other validation functions written like this and they all handle the reference type correctly, which has led me to believe that it is an issue with the enumeration.</p> <pre><code>int val_subscriberType (char str[], const enum ns1__subscriberType *subType ) { if (strcmp(upStr, "PREPAID") == 0) { enum ns1__subscriberType subType = ns1__subscriberType__prepaid; printf("SubscriberFunction: %d \n", subType); return 1; } else if (strcmp(upStr, "POSTPAID") == 0) { enum ns1__subscriberType subType = ns1__subscriberType__postpaid; printf("SubscriberFunction: %d \n", subType); return 1; } return 0; } </code></pre> <p>Main</p> <pre><code>char *recRetTest = "aggressive"; enum ns1__recurrentRetrySchemaType recRet; if ( val_recurrentRetrySchemaType (recRetTest, &amp;recRet)) { printf ("\nRecurrent Retry Schema main: %d \n", recRet); } </code></pre> <p>P.S I've taken out the extra code where I convert the string to upper case etc.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
