FILE* G_fopen_new_misc	(	const char *	dir,
		const char *	element,
		const char *	name
	)

open a new database file

The database file name under the element in the current mapset is created and opened for writing (but not reading). The UNIX fopen( ) routine, with "w" write mode, is used to open the file. If the file does not exist, the NULL pointer is returned. Otherwise the file is positioned at the end of the file and the file descriptor from the fopen( ) is returned.

Parameters

element
name

Returns

FILE* G_fopen_old_misc	(	const char *	dir,
		const char *	element,
		const char *	name,
		const char *	mapset
	)

open a database file for reading

The database file name under the element in the specified mapset is opened for reading (but not for writing). The UNIX fopen( ) routine, with "r" read mode, is used to open the file. If the file does not exist, the NULL pointer is returned. Otherwise the file descriptor from the fopen( ) is returned.

Parameters

element
name
mapset

Returns

int G_open_new_misc	(	const char *	dir,
		const char *	element,
		const char *	name
	)

open a new database file

The database file name under the element in the current mapset is created and opened for writing (but not reading). The UNIX open( ) routine is used to open the file. If the file does not exist, -1 is returned. Otherwise the file is positioned at the end of the file and the file descriptor from the open( ) is returned.

Parameters

element
name

Returns

int
