Name
mysql_real_escape_string - escape string by taking into account charac-
ter set of connection
Synopsis
#include <mysql.h>
unsigned long mysql_real_escape_string(MYSQL * mysql,
char * to,
const char * from,
unsigned long);
Description
This function is used to create a legal SQL string that you can use in
an SQL statement. The given string is encoded to an escaped SQL
string, taking into account the current character set of the connec-
tion.
Parameter
• mysql - a mysql handle, which was previously allocated by
mysql_init(3) and connected by mysql_real_connect(3).
• to - buffer for the encoded string. The size of this buffer must be
length * 2 + 1 bytes: in worst case every character of the from
string needs to be escaped. Additionally a trailing 0 character will
be appended.
• from - a string which will be encoded by mysql_real_escape_string().
• long - the length of the from string.
Return value
Returns the length of the encoded (to) string.
