edt_intfc_read_32

Description

A convenience routine, partly for backward compatability, to access the XILINX interface registers.

The register descriptors used be edt_reg_write() can also be used, since edt_intfc_read_32 masks off

the offset.

Syntax

uint_t

edt_intfc_read_32(EdtDev *edt_p, uint_t offset)

Arguments

edt_p

device struct returned from edt_open

offset

integer offset into XILINX interface, or register descriptor

val

unsigned character value to set

Example

u_int r_actkbs=edt_intfc_read_32(edt_p, EDT_ACT_KBS);

Return

void

edt_msleep

Description

Causes the process to sleep for the specified number of microseconds.

Syntax

#include "edtinc.h"

int edt_msleep(u_int usecs) ;

Arguments

usecs

The number of microseconds for the process to sleep.

Return

0 on success; –1 on error. If an error occurs, call edt_perror() to get the system error message.

edt_alloc

Description

Convenience routine to allocate memory in a system-independent way. The buffer returned is page

aligned. Uses VirtualAlloc on Windows NT systems, valloc on UNIX-based systems.

Syntax

#include "edtinc.h"

int

edt_alloc(int nbytes)
