#### 7.4.28.7 optionGetValue

get a specific value from a hierarcical list

Usage:

    const tOptionValue* res = optionGetValue( pOptValue, valueName );

Where the arguments are:

| Name | Type | Description
| --- | --- | ---------
| pOptValue | `const tOptionValue*` | a hierarchcal value
| valueName | `const char*` | name of value to get
| returns | const tOptionValue* | a compound value structure

This routine will find an entry in a nested value option or configurable. If "valueName" is NULL, then the first entry is returned. Otherwise, the first entry with a name that exactly matches the argument will be returned.

The returned result is NULL and errno is set:

- `EINVAL` - the `pOptValue` does not point to a valid hierarchical option value.
- `ENOENT` - no entry matched the given name.
