STAT_COMPARE

#define STAT_COMPARE	(		bit,
			field
	)

Value:

    if (a->field != b->field)   \
        difference |= bit;

Function Documentation

fd2fpath_malloc()

char* fd2fpath_malloc

(

int

fd

)

Definition at line 26 of file fileutils.c.

fileutils_calcdirlevel()

short int fileutils_calcdirlevel

(

const char *

path

)

Calculates directory level of a canonized path (actually it just counts "/"-s)

Parameters

[in]

path

Canonized path (with realpath())

Return values

zero	or prositive Direcory level
negative	Got error, while calculation. Error-code is placed to errno.

fileutils_copy()

int fileutils_copy	(	const char *	path_from,
		const char *	path_to
	)

Copies file.

Parameters

[in]	path_from	Source file path
[in]	path_to	Destination file path

Return values

zero	Successfully copied
non-zero	Got error, while copying

Definition at line 78 of file fileutils.c.

Here is the caller graph for this function:

mkdirat_open()

int mkdirat_open	(	const char *const	dir_path,
		int	dirfd_parent,
		mode_t	dir_mode
	)

Combination of mkdirat() and openat()

Parameters

[in]	dir_path	Path to directory to create and open
[in]	dirfd_parent	File descriptor of directory for relative paths
[in]	dir_mode	Modes for newly created directory (e.g. 750)

Return values

dirfd	File descriptor to newly created directory
NULL	On error
