GET-STRING function

Returns the null-terminated character string at the specified memory location as a CHARACTER value (not including the null terminator) or the number of bytes specified starting from the specified memory location as a CHARACTER value.

Syntax 

 

GET-STRING ( source , position [ , numbytes ] )

source

A function or variable that returns a RAW or MEMPTR value. If source is the Unknown value (?), GET-STRING returns the Unknown value (?).

position

An integer value greater than 0 that indicates the byte position where you want to find the information. If position is greater than the length of source, the AVM returns the Unknown value (?). If position is less than 1, the AVM generates a run-time error.

numbytes

An integer value greater than 0 that indicates how many bytes to convert into the CHARACTER value that is returned. If numbytes is not specified, or is -1, GET-STRING( ) returns all bytes until it encounters a NULL value.

Examples 

For examples of how to use the GET-STRING function, see the GET-BYTE function reference entry.
