mbkenv(3) set user preferences

SYNOPSYS

#include "mut.h"
void mbkenv();

DESCRIPTION

The mbkenv function set the user preferences through unix environment variables. if all the variables are not defined, default values are used.

MBK_WORK_LIB
internally char *WORK_LIB, sets the working directory for reading and writting, result of a savephfig for example. Its value is "." by default.
MBK_CATA_LIB
internally char **CATA_LIB, sets the working directories for reading only. This is a set of pathes, like the unix PATH variable. It is used in loadlofig for example. Its value is "." by default.
MBK_CATAL_NAME
internally char *CATAL_NAME, sets the name of the catalog file, needed to know where to stop a flatten, and so on. Set to "CATAL" by default.
MBK_SEPAR
internally char SEPAR, sets the character used for string concatenation. Used for example in concatname. By default it is ".".
MBK_VDD
internally char *VDD, sets the name to be used as power level recognition pattern by the tools based upon mbk that needs to identify supplies. The default is "vdd".
MBK_VSS
internally char *VSS, sets the name to be used as ground level recognition pattern by the tools based upon mbk that needs to identify supplies. The default is "vss".
MBK_TRACE_MODE
internally char TRACE_MODE, output information in each mbk access function it enters. Used for debugging purposes. By default it is 'N'.
MBK_DEBUG_MODE
internally char DEBUG_MODE, output information in function that makes a check on its values : mostly parsers for debug. It is very verbose, and mostly unusable. No mbk function take care of it. By default it is 'N'.
MBK_FAST_MODE
internally char FAST_MODE. If set to 'Y', no consistency checked are performed on many mbk functions. This can work only on a program that is warrantied to be bugless, else undefined results would occur. By default it is 'N'.
MBK_IN_LO
internally char IN_LO[5]. Defines the logical input format demanded by the user. See MBK_IN_LO(1) for a list of valid formats. By default its value is "al".
MBK_OUT_LO
internally char OUT_LO[5]. Defines the logical input format demanded by the user. See MBK_OUT_LO(1) for a list of valid formats. By default its value is "al".
MBK_IN_PH
internally char IN_PH[5]. Defines the logical input format demanded by the user. See MBK_IN_PH(1) for a list of valid formats. By default its value is "ap".
MBK_OUT_PH
internally char OUT_PH[5]. Defines the logical input format demanded by the user. See MBK_OUT_PH(1) for a list of valid formats. By default its value is "ap".
MBK_SCALE_X
internally long SCALE_X. Defines a scale factor for all coordinates, in order to be able to use files that works with half lambda rules for example. Parsers, drivers and genlib's macros use it extensivly. Its value is ten by default.
MBK_IN_FILTER
internaly IN_FILTER. Filter string for reading compressed Alliance files. It has no value by default, means no filter is used.
MBK_OUT_FILTER
internaly OUT_FILTER. Filter string for writing compressed Alliance files. It has no value by default, means no filter is used.
MBK_FILTER_SFX
internaly FILTER_SFX. Extention of compressed files. It has no value by default, means no filter is used.

EXAMPLE

#include "mut.h"
#include "mlo.h"
lofig_list *load_fig(name)
char *name;
{
   mbkenv(); /* make sure the good environnement is used */
   return getlofig(name, 'A');
}
