Function Documentation

int EBF_stream ESX_change

(

ESX_ctl *

esx

)

Creates a new output file.

Returns:

A pointer to the stream

Parameters:

esx

The control structure

void ESX_close

(

ESX_ctl *

esx

)

Closes the output stream.

Parameters:

esx

The control block

int ESX_dir_write	(	ESX_ctl *	esx,
		EBF_dir *	dir
	)

Writes the event.

Returns:

Status

Parameters:

	esx	The control structure
	dir	The directory of the event to write out

int __inline ESX_evt_declare

(

ESX_ctl *

esx

)

Declares an input event has been seen. This information is used to determine whether to trigger the creation of a new output file.

Parameters:

esx

The control structure

static unsigned int get_number

(

const char *

s

)

[static]

Parses the input string, returning the integer equivalent.

Returns:

The integer equivalent

Parameters:

s

The string to parse

The string must be in the form of a conventionally specified C integer and may optionally be followed by the suffix K, M, C. These give the scaling or units

-K Hexadecimal kilobytes (scale by 1024) -M Hexadecimal megabytes (scale by 1024 * 1024) -B LCB blocks (scale by 128, max of 31) Examples
s result
"100" 100
"100K" 100*1024
"100M" 100*1024*124
"31C 31*128
