This function queries a dictionary for a key. A key as read from an
|
||||
ini file is given as "section:key". If the key cannot be found,
|
||||
the notfound value is returned.
|
||||
|
||||
Supported values for integers include the usual C notation
|
||||
so decimal, octal (starting with 0) and hexadecimal (starting with 0x)
|
||||
are supported. Examples:
|
||||
|
||||
"42" -> 42
|
||||
"042" -> 34 (octal -> decimal)
|
||||
"0x42" -> 66 (hexa -> decimal)
|
||||
|
||||
Warning: the conversion may overflow in various ways. Conversion is
|
||||
totally outsourced to strtol(), see the associated man page for overflow
|
||||
handling.
