From 2128f6f364aefa3a247524463593e49d163e5057 Mon Sep 17 00:00:00 2001 From: Jim Meyering Date: Mon, 19 Nov 2001 11:06:32 +0000 Subject: [PATCH] (TMP_MAX): Remove; no longer needed. (TEMPORARIES): New macro. (__gen_tempname): Use TEMPORARIES rather than TMP_MAX. This removes an artificial limitation (e.g. HP-UX 10.20, where TMP_MAX is 17576). --- lib/tempname.c | 13 ++++++++----- 1 file changed, 8 insertions(+), 5 deletions(-) diff --git a/lib/tempname.c b/lib/tempname.c index 0c9853e3b6..deae318cfd 100644 --- a/lib/tempname.c +++ b/lib/tempname.c @@ -32,9 +32,6 @@ #ifndef P_tmpdir # define P_tmpdir "/tmp" #endif -#ifndef TMP_MAX -# define TMP_MAX 238328 -#endif #ifndef __GT_FILE # define __GT_FILE 0 # define __GT_BIGFILE 1 @@ -123,6 +120,11 @@ char *getenv (); # define uint64_t uintmax_t #endif +/* The total number of temporary file names that can exist for a given + template is 62**6.
