| f__FIO__read__text | A wrapper function for f__FIO__read. |
| f__FIO__read__data | A wrapper function for f__FIO__read. |
| f__FIO__read__text__until | It reads textual data until a given pattern is matched. |
| f__FIO__read__data__until | It reads binary data until a given pattern is matched. |
| f__FIO__set__filedescriptor__previousline | It sets the file descriptor to the begin of the previous line. |
| f__FIO__read__data__TLV | It reads binary data until a full ASN.1 TLV structure is read. |
| f__FIO__chdir | It changes the current directory. |
| f_FIO_mkdir | Create a new directory |

| f_FIO_fileOrDirExists | Checks the existence of files and directories. |
| f_FIO_stat | Query the permissions of the file or directory. |
| f_FIO_chmod | Change the permissions of the file or directory. |
Opens a file with the given name in the given mode. It creates the file if it doesn’t exist. (For internal use only.)
| NAME | The name of the file. |
| FLAGS | The way to open the file. |
The file descriptor for the file or -1 on error. The error message is available through the f__FIO__get__error function.
A wrapper function for f__FIO__open. It opens the file with the given name for writing only in exclusive mode. If the file already exists it is opened in appending mode.
| NAME | The name of the file. |
What f__FIO__open returns or -1 if the file cannot be locked.
A wrapper function for f__FIO__open. It opens the file with the given name for reading and writing in exclusive mode. If the file already exists it is opened in appending mode.
| NAME | The name of the file. |
What f__FIO__open returns or -1 if the file cannot be locked.
A wrapper function for f__FIO__open. It opens the file with the given name for reading and writing in exclusive mode. If the file was not empty it is truncated.
| NAME | The name of the file. |
What f__FIO__open returns or -1 if the file cannot be locked.
Reads a given number of bytes to a given buffer from a file associated with the given file descriptor. (For internal use only.)
| FD | A file descriptor. |
| DATA | The buffer where the data will be stored. |
| BYTES | The number of bytes to read. |
The number of bytes read or -1 if the requested number of bytes couldn’t be read.
Create a new directory
| p_dir_name | in charstring - name of the directory to create |
| boolean | indicate the successful or unsuccessful directory creation |
In the case of unsuccessful operation the cause of the error can be queried by the f_FIO_get_error_code, f_FIO_get_error_string functions
The path to the directory must exist, so the existence of the path should be checked, and the missing directories should be created recursively.
Removes a directory
| p_dir_name | in charstring - name of the directory to remove |
| boolean | indicate the successful or unsuccessful directory creation |
In the case of unsuccessful operation the cause of the error can be queried by the f_FIO_get_error_code, f_FIO_get_error_string functions
The directories must be empty, so the child directories should be cleaned and deleted recursively.
Change the permissions of the file or directory.
| p_name | in charstring - name of the file or directory to check |
| p_permissions | in FIO_permissions - the permissions of the object |
| boolean | indicate sucessfull execution |
-
Change the permissions of the file or directory according to the p_permissions. If the value of the field is:
