Data Fields
int(*	stdin_read )(char *data, unsigned int len)
	Function to call when performing a STDIN read.
int(*	stdout_write )(char *data, unsigned int len)
	Function to call when performing a STDOUT write.
int(*	stderr_write )(char *data, unsigned int len)
	Function to call when performing a STDERR write.

Detailed Description

Standard I/O hook structure.

This structure provides optional callback hooks for code wishing to respond to reads from STDIN or writes to STDOUT or STDERR. Any function that code does not wish to handle should be left as a null pointer.

Field Documentation

stdin_read

int(* stdio_t::stdin_read) (char *data, unsigned int len)

Function to call when performing a STDIN read.

Parameters

[out]	data	Pointer to data buffer to place the read data
[in]	len	Length of data in bytes expected to be read

Returns

Actual number of bytes read into data, not to exceed the original length.

stdout_write

int(* stdio_t::stdout_write) (char *data, unsigned int len)

Function to call when performing a STDOUT write.

Parameters

[in]	data	Pointer to data buffer containing the data to write
[in]	len	Length of data in bytes expected to be written

Returns

Actual number of bytes written from data, not to exceed the original length.

stderr_write

int(* stdio_t::stderr_write) (char *data, unsigned int len)

Function to call when performing a STDERR write.

Parameters

[in]	data	Pointer to data buffer containing the data to write
[in]	len	Length of data in bytes expected to be written

Returns

Actual number of bytes written from data, not to exceed the original length.
