init_dynarray_intvar_from_file()

long init_dynarray_intvar_from_file	(	char *	buffer,
		size_t	size,
		char **	buffer_act,
		IO_CACHE *	f
	)

TODO - Improve this function to use String and avoid this weird computation to calculate the size of the buffers.

Particularly, this function is responsible for restoring IGNORE_SERVER_IDS list of servers whose events the slave is going to ignore (to not log them in the relay log).

Items being read are supposed to be decimal output of values of a type shorter or equal of long and separated by the single space.

Parameters

buffer	Put the read values in this static buffer
size	Size of the static buffer
buffer_act	Points to the final buffer as dynamic buffer may be used if the static buffer is not big enough.
f	IO_CACHE of the replication info file.

Return values

>=	0 Number or read bytes
<	0 An error

init_floatvar_from_file()

long init_floatvar_from_file	(	float *	var,
		IO_CACHE *	f,
		float	default_val
	)

Tries to read a float value from the IO_CACHE f current line - being a line a string terminated by '
'.

Parameters

var	Put the read value in this parameter.
f	IO_CACHE of the replication info file.
default_val	Default value to be assigned in case unable to read bytes.

Return values

>=	0 Number or read bytes
<	0 An error

init_intvar_from_file()

long init_intvar_from_file	(	int *	var,
		IO_CACHE *	f,
		int	default_val
	)

Tries to read an integer value from the IO_CACHE f current line - being a line a string terminated by '
'.

Parameters

var	Put the read value in this parameter.
f	IO_CACHE of the replication info file.
default_val	Default value to be assigned in case unable to read bytes.

Return values

>=	0 Number or read bytes
<	0 An error

init_strvar_from_file()

long init_strvar_from_file	(	char *	var,
		size_t	max_size,
		IO_CACHE *	f,
		const char *	default_val
	)

Tries to read a string of maximum size max_size from the IO_CACHE f current line - being a line a string terminated by '
'.

Parameters

var	Put the read values in this static buffer
max_size	Size of the static buffer
f	IO_CACHE of the replication info file.
default_val	Default value to be assigned in case unable to read bytes.

Return values

>=	0 Number or read bytes
<	0 An error

init_ulongvar_from_file()

long init_ulongvar_from_file	(	ulong *	var,
		IO_CACHE *	f,
		ulong	default_val
	)

Tries to read an unsigned integer value from the IO_CACHE f current line - being a line a string terminated by '
'.

Parameters

var	Put the read value in this parameter.
f	IO_CACHE of the replication info file.
default_val	Default value to be assigned in case unable to read bytes.

Return values

>=	0 Number or read bytes
<	0 An error
