NAME

viPeek8 − Reads an 8-bit value from the specified address location

SYNOPSIS

viPeek8(ViSession vi, ViAddr addr, ViPUInt8 val8);

Description

 
This function reads an 8-bit value from the address location specified in addr.  The address must be a valid memory address in the current process mapped by a previous viMapAddress call.
 

Parameters

vi An input parameter. Unique logical identifier to a session. 
 

addr An input parameter. Specifies the source address to read the value. 
 

val8 An output parameter. Data read from bus (8-bits). 
 
 
NOTE ViAddr is defined as a void *.  To do pointer arithmetic, you must cast this to an appropriate type (ViUInt8). Then be sure the offset is correct for the type of pointer you are using.  For example, (ViUInt8 *)addr + 4 points to the same location as (ViUInt16 *)addr + 2.
 
 

Return Values

 
None.
