From 70b77a0fc329e2e205a596a738c7307d354e7b1c Mon Sep 17 00:00:00 2001 From: Mike Gabriel Date: Tue, 14 Apr 2015 09:24:55 +0200 Subject: library clean-up: Don't build and link libXfont.a anymore. Use system's libXfont shared library and link dynamically. --- nx-X11/lib/font/fontfile/gunzip.c | 227 -------------------------------------- 1 file changed, 227 deletions(-) delete mode 100644 nx-X11/lib/font/fontfile/gunzip.c (limited to 'nx-X11/lib/font/fontfile/gunzip.c') diff --git a/nx-X11/lib/font/fontfile/gunzip.c b/nx-X11/lib/font/fontfile/gunzip.c deleted file mode 100644 index 8c9c317aa..000000000 --- a/nx-X11/lib/font/fontfile/gunzip.c +++ /dev/null @@ -1,227 +0,0 @@ -/* $Xorg: gunzip.c,v 1.3 2000/08/17 19:46:37 cpqbld Exp $ */ -/* lib/font/fontfile/gunzip.c - written by Mark Eichin September 1996. - intended for inclusion in X11 public releases. */ -/* $XFree86: xc/lib/font/fontfile/gunzip.c,v 1.4 2000/09/19 12:46:08 eich Exp $ */ - -#ifdef HAVE_CONFIG_H -#include -#endif -#include -#include -#include - -typedef struct _xzip_buf { - z_stream z; - int zstat; - BufChar b[BUFFILESIZE]; - BufChar b_in[BUFFILESIZE]; - BufFilePtr f; -} xzip_buf; - -static int BufZipFileClose ( BufFilePtr f, int flag ); -static int BufZipFileFill ( BufFilePtr f ); -static int BufZipFileSkip ( BufFilePtr f, int c ); -static int BufCheckZipHeader ( BufFilePtr f ); - -BufFilePtr -BufFilePushZIP (BufFilePtr f) -{ - xzip_buf *x; - - x = (xzip_buf *) xalloc (sizeof (xzip_buf)); - if (!x) return 0; - /* these are just for raw calloc/free */ - x->z.zalloc = Z_NULL; - x->z.zfree = Z_NULL; - x->z.opaque = Z_NULL; - x->f = f; - - /* force inflateInit to allocate it's own history buffer */ - x->z.next_in = Z_NULL; - x->z.next_out = Z_NULL; - x->z.avail_in = x->z.avail_out = 0; - - /* using negative windowBits sets "nowrap" mode, which turns off - zlib header checking [undocumented, for gzip compatibility only?] */ - x->zstat = inflateInit2(&(x->z), -MAX_WBITS); - if (x->zstat != Z_OK) { - xfree(x); - return 0; - } - - /* now that the history buffer is allocated, we provide the data buffer */ - x->z.next_out = x->b; - x->z.avail_out = BUFFILESIZE; - x->z.next_out = x->b_in; - x->z.avail_in = 0; - - if (BufCheckZipHeader(x->f)) { - xfree(x); - return 0; - } - - return BufFileCreate((char *)x, - BufZipFileFill, - 0, - BufZipFileSkip, - BufZipFileClose); -} - -static int -BufZipFileClose(BufFilePtr f, int flag) -{ - xzip_buf *x = (xzip_buf *)f->private; - inflateEnd (&(x->z)); - BufFileClose (x->f, flag); - xfree (x); - return 1; -} - -/* here's the real work. - -- we need to put stuff in f.buffer, update f.left and f.bufp, - then return the first byte (or BUFFILEEOF). - -- to do this, we need to get stuff into avail_in, and next_in, - and call inflate appropriately. - -- we may also need to add CRC maintenance - if inflate tells us - Z_STREAM_END, we then have 4bytes CRC and 4bytes length... - gzio.c:gzread shows most of the mechanism. - */ -static int -BufZipFileFill (BufFilePtr f) -{ - xzip_buf *x = (xzip_buf *)f->private; - - /* we only get called when left == 0... */ - /* but just in case, deal */ - if (f->left >= 0) { - f->left--; - return *(f->bufp++); - } - /* did we run out last time?
