From ae70f5c6479514690c7b1aea57f26650ce918779 Mon Sep 17 00:00:00 2001 From: Morten Welinder Date: Thu, 15 Feb 2001 21:23:50 +0000 Subject: [PATCH] (PSDRV_AFMGetCharMetrics): Use unsigned chars (since isspace is used). (PSDRV_AFMParse): Don't crash on missing font name. Use unsigned chars. Fix peculiar inconsistent indentation. Don't leak a FILE. Catch problematic files with no line feed in them. Don't mix characters and integers. Don't overrun the buffer. --- dlls/wineps/afm.c | 60 ++++++++++++++++++++++++++--------------------- 1 file changed, 33 insertions(+), 27 deletions(-) diff --git a/dlls/wineps/afm.c b/dlls/wineps/afm.c index c051e56a38..46e9595146 100644 --- a/dlls/wineps/afm.c +++ b/dlls/wineps/afm.c @@ -34,8 +34,8 @@ FONTFAMILY *PSDRV_AFMFontList = NULL; */ static void PSDRV_AFMGetCharMetrics(AFM *afm, FILE *fp) { - char line[256], valbuf[256]; - char *cp, *item, *value, *curpos, *endpos; + unsigned char line[256], valbuf[256]; + unsigned char *cp, *item, *value, *curpos, *endpos; int i; AFMMETRICS *metric; @@ -63,7 +63,7 @@ static void PSDRV_AFMGetCharMetrics(AFM *afm, FILE *fp) while(isspace(*value)) value++; cp = endpos = strchr(value, ';'); - if (!cp) { ERR("missing ;, failed.\n"); return; } + if (!cp) { ERR("missing ;, failed.
