注: Output files (.wrt) are generated only if the generation of these files is enabled in the General tab of the Profile Settings - Results dialog.

Include file

Kernel.bdh

Syntax

WriteData( in sData    : string,
           in nDataLen : number optional,
           in nOption  : number optional ): boolean;

Return value

true if successful
false otherwise

Parameter	Description
sData	String buffer containing the data to write to the output file.
nDataLen	Number of bytes to be written to the output file (optional).
nOption	Specifies the format used for writing (optional). Can be one of the following: OPT_WRITEDATA_PRINTABLE (default). If the string buffer contains only printable characters, the ASCII representation of the data is printed. Otherwise, a mixed notation is used OPT_WRITEDATA_HEX. A mixed notation is used for writing OPT_WRITEDATA_HEXONLY. The data is printed in hexadecimal notation
