Search::Dict(3pm) Perl Programmers Reference Guide Search::Dict(3pm)NAME
Search::Dict - look - search for key in dictionary file
SYNOPSIS
use Search::Dict;
look *FILEHANDLE, $key, $dict, $fold;
use Search::Dict;
look *FILEHANDLE, $params;
DESCRIPTION
Sets file position in FILEHANDLE to be first line greater than or equal (stringwise) to $key. Returns the new file position, or -1 if an
error occurs.
The flags specify dictionary order and case folding:
If $dict is true, search by dictionary order (ignore anything but word characters and whitespace). The default is honour all characters.
If $fold is true, ignore case. The default is to honour case.
If there are only three arguments and the third argument is a hash reference, the keys of that hash can have values "dict", "fold", and
"comp" or "xfrm" (see below), and their corresponding values will be used as the parameters.
If a comparison subroutine (comp) is defined, it must return less than zero, zero, or greater than zero, if the first comparand is less
than, equal, or greater than the second comparand.
If a transformation subroutine (xfrm) is defined, its value is used to transform the lines read from the filehandle before their
comparison.

dictNext(3) util/dict.h dictNext(3)NAME
dictNext - search for next value in dictionary.
SYNOPSIS
#include <util/dict.h>
void *dictNext(dictCtx dict, char **id, void **plock);
ARGUMENTS
dict - dictionary to iterate over.
id - pointer to identifier of last item found, or
pointer to NULL to retrieve first.
plock - place for value lock (or NULL).
DESCRIPTION
Can be used to iterate through values in the dictionary. The order is the order of the hash of the ids, which isn't usefully externally.
Will return the value if found, or NULL if not. If <plock> is non-NULL, then the lock returned in <plock> will be associated with the
returned value. Until this lock is passed to dictReleaseLock(), the value will not be passed to the dictCleanupFunc callback (see dict-
Cleanup()).
MT-Level: Safe if <dict> thread-safe.
RETURN VALUE
plock - set to value lock.
id - pointer to id of found value
