1LOADLOFIG(3) MBK LOGICAL UTILITY FUNCTIONS LOADLOFIG(3)

6 loadlofig - load a new logical cell model from disk

9 #include "mlo.h"
10 void loadlofig(ptfig, figname, mode)
11 lofig_list ∗ptfig;
12 char ∗figname;
13 char mode;
14
16 ptfig Pointer to an allocated but empty lofig
17
18 figname Name of the figure to be loaded
19
20 mode Loading mode
21
23 loadlofig fills the lofig pointed to by ptfig with the contents of a
24 disk file called figname. The loading mode may be either 'A', then the
25 entire content is parsed, or 'P' then only connectors and extrernal
26 signals are loaded in memory, or 'C', that loads the "complement" of an
27 already partially loaded cell in order to keep the same pointer when
28 accessing the same file.
29 The loadlofig(3) function in fact performs a call to a parser, chosen
30 by the MBK_IN_LO(1) environment variable. The directories searched for
31 the file are first the one sets by MBK_WORK_LIB(1) and then, in the
32 described order, the ones set by MBK_CATA_LIB(1). See MBK_IN_LO(1),
33 MBK_WORK_LIB(1), MBK_CATA_LIB(1) and mbkenv(3) for details.
34
36 Some errors resulting from a call to loadlofig are due to the parsers,
37 and are prefixed by the parser format (pf).
38 "∗∗∗ mbk error ∗∗∗ not supported logical input format 'xxx'"
39 The environment variable MBK_IN_LO is not set to a legal logical
40 format.
41 "∗∗∗ mbk error ∗∗∗ pfloadlofig : could not open file figname"
42 No file called figname.ext, where ext is the file format exten‐
43 sion, has been found in the directories set by the environment.
44 "∗∗∗ mbk error ∗∗∗ pfloadlofig : syntax error line x parsing fig‐
45 name.ext"
46 Either the file has been corrupted and its syntax is not legal,
47 or there is a bug in the given parser.
