gp_compose_path

#define gp_compose_path	(		dir,
			...
	)		gp_compose_path_(dir, ##__VA_ARGS__, NULL);

Builds a path from directories passsed in arguments.

The returned path is normalized, i.e. there are no two path delimiters '/' next to each other.

Parameters

dir	A first directory in path.
...	A NULL terminated list of path components.

Returns

A newly allocated buffer with path or NULL in a case of a failure.

Enumeration Type Documentation

gp_mkpath_flags

enum gp_mkpath_flags

Enumerator
GP_MKPATH_HAS_FILE	Last component in path if it does not end with slash is ignored

Function Documentation

gp_mkpath()

int gp_mkpath	(	const char *	base_path,
		const char *	path,
		enum gp_mkpath_flags	flags,
		int	mode
	)

Creates a path, if it does not exists.

Works similar to 'mkdir -p'. Hoever if last compoment of the path is a file, i.e. last path component does not end with '/' it's ignored.

Parameters

base_path	A path to create the directories under, can be NULL.
path	A path, one or more directories.
flags	An enum gp_mkpath_flags.
mode	A mode for the directories created in the path.

Returns

Zero on success, non-zero otherwise and errno is set.

gp_user_home()

char * gp_user_home

(

void

)

Returns a user home directory.

The home directory is validated to be an absolute path.

Returns

An absolute path to the user home directory or NULL on failure.
