get a specific value from a hierarcical list
Usage:
const tOptionValue* res = optionGetValue( pOptValue, valueName ); |
Where the arguments are:
Name | Type | Description | |
--- | --- | --------- | |
pOptValue | | a hierarchcal value | |
valueName | | 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.
