man getlofig (3): give back a pointer to a lofig

SYNOPSYS

#include "mlo.h"
lofig_list *getlofig(figname, mode)
char *figname;
char mode;

PARAMETERS

figname: Name of the figure to be created
mode: Demanded mode for the figure

DESCRIPTION

getlofig returns a pointer to the figure called figname with the warranty that the expected information is present in memory.
If mode is 'A' then the figure has all its lists filled, else the figure may either be complete or interface only.
This function allows to completly mask disk access for applications programs. If the figure is in memory, with the specified mode, then the function returns the appropriate pointer. Else, the function performs a call to the loadlofig(3) and returns a pointer to the loaded figure.

RETURN VALUE

getlofig returns a pointer to the wanted figure.

ERRORS

getlofig cannot give any errors, but the subsequent calls it performs to parsers do. So the source of trouble may be the call to getlofig. See loadlofig(3) for details.

EXAMPLE

#include "mlo.h"
lofig_list *na2_y()
{
   /* find in memory or load from disk na2_y */
   return getlofig("na2_y", 'A');
}
