char* config_StringEscape ( const char * psz_string )

This function will escape a string that can be unescaped by config_StringUnescape.

The returned value is allocated by it. You have to free it once you do not need it anymore (unlike config_StringUnescape). If NULL is given as parameter nothing will be done (NULL will be returned).

The escaped characters are ' " and \

char* config_StringUnescape ( char * psz_string )

This function will unescape a string in place and will return a pointer on the given string.

No memory is allocated by it (unlike config_StringEscape). If NULL is given as parameter nothing will be done (NULL will be returned).

The following sequences will be unescaped (only one time): \ \' and "
