Function Documentation

G_gisbase()

const char* G_gisbase

(

void

)

Get full path name of the top level module directory.

Returns the full path name of the top level directory for GRASS programs. This directory will have subdirectories which will contain modules and files required for the running of the system. Some of these directories are:

bin    commands run by the user
etc    modules and data files used by GRASS commands

The use of G_gisbase() to find these subdirectories enables GRASS modules to be written independently of where the GRASS system is actually installed on the machine. For example, to run the module sroff in the GRASS etc directory:

char command[200];

sprintf(command, "%s/etc/sroff", G_gisbase());
G_spawn(command, "sroff", NULL);

Returns

pointer to a string
