◆ gru_io_open_file()
Tries to safely open a file (ie.: creating directories and stuff).
Truncates the file
- Parameters
-
dir | directory of the file |
name | name of the file |
status | status structure containing error code/description in case of failure |
- Returns
- a FILE descriptor for the opened file or NULL otherwise (in this case, check status)
◆ gru_io_open_file_path()
Tries to safely open a file (ie.: creating directories and stuff).
Truncates the file
- Parameters
-
path | path to the file |
status | status structure containing error code/description in case of failure |
- Returns
- a FILE descriptor for the opened file or NULL otherwise (in this case, check status)
◆ gru_io_open_file_read()
Tries to safely open a file (ie.: creating directories and stuff)
- Parameters
-
dir | directory of the file |
name | name of the file |
status | status structure containing error code/description in case of failure |
- Returns
- a FILE descriptor for the opened file or NULL otherwise (in this case, check status)
◆ gru_io_open_file_read_path()
Tries to safely open a file (ie.: creating directories and stuff)
- Parameters
-
path | path to the file |
status | status structure containing error code/description in case of failure |
- Returns
- a FILE descriptor for the opened file or NULL otherwise (in this case, check status)
◆ gru_io_open_unique_file()
Tries to safely open a file (ie.: creating directories and stuff)
- Parameters
-
dir | directory of the file |
name | name of the file |
status | status structure containing error code/description in case of failure |
- Returns
- a FILE descriptor for the opened file or NULL otherwise (in this case, check status)
◆ gru_io_read_text_into()
Reads the file pointed by file into the destination buffer.
The memory for the allocation buffer is allocated as needed and must be free'd after use
- Parameters
-
dest | the destination buffer |
file | the file to read |
status | status structure containing error code/description in case of failure |
- Returns
- the amount of bytes read of 0 in case of error
◆ gru_io_remap()
IO utilities.
Lot's of nonsense here. Most will be fixed/rewritten in the future. Remaps IO from one file descriptor to a file pointed by dir/name
- Parameters
-
dir | directory of the file |
name | name of the file |
fd | file descriptor to remap |
status | status structure containing error code/description in case of failure |
- Returns
- true if remapped or false otherwise (in this case, check status)
