bool get_file_options_ulllist	(	const char *&	ptr,
		const char *	end,
		const char *	line,
		uchar *	base,
		File_option *	parameter,
		MEM_ROOT *	mem_root
	)

Parser for FILE_OPTIONS_ULLLIST type value.

Parameters:

[in,out]	ptr	pointer to parameter
[in]	end	end of the configuration
[in]	line	pointer to the line begining
[in]	base	base address for parameter writing (structure like TABLE)
[in]	parameter	description
[in]	mem_root	MEM_ROOT for parameters allocation

const char* parse_escaped_string	(	const char *	ptr,
		const char *	end,
		MEM_ROOT *	mem_root,
		LEX_STRING *	str
	)

parse \n delimited escaped string.

Parameters:

ptr	pointer on string beginning
end	pointer on symbol after parsed string end (still owned by buffer and can be accessed
mem_root	MEM_ROOT for parameter allocation
str	pointer on string, where results should be stored

Return values:

0	error
\::	pointer on symbol after string

my_bool read_escaped_string	(	const char *	ptr,
		const char *	eol,
		LEX_STRING *	str
	)

read escaped string from ptr to eol in already allocated str.

Parameters:

ptr	pointer on string beginning
eol	pointer on character after end of string
str	target string

Return values:

FALSE	OK
TRUE	error

my_bool rename_in_schema_file	(	THD *	thd,
		const char *	schema,
		const char *	old_name,
		const char *	new_db,
		const char *	new_name
	)

Renames a frm file (including backups) in same schema.

thread handler

Parameters:

schema	name of given schema
old_name	original file name
new_db	new schema
new_name	new file name

Return values:

0	OK
1	Error (only if renaming of frm failed)

my_bool sql_create_definition_file	(	const LEX_STRING *	dir,
		const LEX_STRING *	file_name,
		const LEX_STRING *	type,
		uchar *	base,
		File_option *	parameters
	)

Write new .frm.

Parameters:

dir	directory where put .frm
file_name	.frm file name
type	.frm type string (VIEW, TABLE)
base	base address for parameter reading (structure like TABLE)
parameters	parameters description

Return values:

FALSE	OK
TRUE	error

File_parser* sql_parse_prepare	(	const LEX_STRING *	file_name,
		MEM_ROOT *	mem_root,
		bool	bad_format_errors
	)

Prepare frm to parse (read to memory).

Parameters:

file_name	path & filename to .frm file
mem_root	MEM_ROOT for buffer allocation
bad_format_errors	send errors on bad content

Note:

returned pointer + 1 will be type of .frm

Returns:

0 - error
