str	pointer on string, where results should be stored

Returns

Pointer on symbol after string

Return values

0

error

static

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

sql_parse_prepare()

File_parser * sql_parse_prepare	(	const LEX_STRING *	file_name,
