tk_uid
Tk_GetUid(3TK) Tk Library Procedures Tk_GetUid(3TK)
__________________________________________________________________________________________________________________________________________________
NAME
Tk_GetUid, Tk_Uid - convert from string to unique identifier
SYNOPSIS
#include <tk.h>
Tk_Uid
Tk_GetUid(string)
ARGUMENTS
char *string (in) String for which the corresponding unique identifier is desired.
_________________________________________________________________
DESCRIPTION
Tk_GetUid returns the unique identifier corresponding to string. Unique identifiers are similar to atoms in Lisp, and are used in Tk to
speed up comparisons and searches. A unique identifier (type Tk_Uid) is a string pointer and may be used anywhere that a variable of type
``char *'' could be used. However, there is guaranteed to be exactly one unique identifier for any given string value. If Tk_GetUid is
called twice, once with string a and once with string b, and if a and b have the same string value (strcmp(a, b) == 0), then Tk_GetUid will
return exactly the same Tk_Uid value for each call (Tk_GetUid(a) == Tk_GetUid(b)). This means that variables of type Tk_Uid may be com-
pared directly (x == y) without having to call strcmp. In addition, the return value from Tk_GetUid will have the same string value as its
argument (strcmp(Tk_GetUid(a), a) == 0).
KEYWORDS
atom, unique identifier
