Function Documentation

G_recursive_copy()

int G_recursive_copy	(	const char *	src,
		const char *	dst
	)

Copy recursively source directory to destination directory.

RULE:

1. If destination does not exist, copy source to destination as expected.
2. If destination already exists and it's a file, destination will be deleted first and apply RULE 1.
3. If destination already exists which is a directory and source is a file, try to copy source to destination directory.
4. If destination already exists which is a directory and source is also a directory, try to copy all contents in source to destination directory.

This rule is designed according to general/manage/lib/copy.sh.

POSSIBLE CASES:

* if src is a file:
*      if dst does not exist:
*              copy src to dst                         RULE 1
*      if dst is a file:
*              delete dst and copy src to dst          RULE 2
*      if dst is a directory:
*              try recursive_copy(src, dst/src)        RULE 3
* if src is a directory:
*      if dst does not exist:
*              copy src to dst                         RULE 1
*      if dst is a file:
*              delete dst and copy src to dst          RULE 2
*      if dst is a directory:
*              try                                     RULE 4
*              for i in `ls src`
*              do
*                      recursive_copy(src/$i, dst/$i)
*              done
*
