* \brief Get full path name of the top level module directory
16
*
17
* Returns the full path name of the top level directory for GRASS
18
* programs. This directory will have subdirectories which will
19
* contain modules and files required for the running of the
20
* system. Some of these directories are:
21
22
\verbatim
23
bin commands run by the user
24
etc modules and data files used by GRASS commands
25
\endverbatim
26
27
* The use of G_gisbase() to find these subdirectories enables GRASS
28
* modules to be written independently of where the GRASS system is
29
* actually installed on the machine. For example, to run the module
30
* <i>sroff</i> in the GRASS <i>etc</i> directory:
31
32
\code
33
char command[200];
34
35
sprintf(command, "%s/etc/sroff", G_gisbase());
36
G_spawn(command, "sroff", NULL);
37
\endcode
38
*
39
* \return pointer to a string
