LockStringArray - Lock an array of string data to memory |
Top Previous Next |
Syntax
<nAddress> := LockStringArray( <aStringData>, [<nType] )
Parameters
<aStringData>
An array (list) containing strings to be committed to memory.
<nType>
Type of string data to be written to memory. This value can be STRINGTYPE_BINARY, STRINGTYPE_BINARY0, STRINGTYPE_TEXT, STRINGTYPE_UNICODETEXT. Specifying this parameter requests character set conversions while copying the string data. Default is STRINGTYPE_BINARY. Checking the type of the written array data with LockStringType will always return STRINGTYPE_BINARY.
Return value
The memory address where the array starts.
Description
LockStringArray allocates a memory block for <aStringData> and writes the string array contained in <aStringData> to that block. Necessary character set conversions are applied while the data is being moved if a string type other than STRINGTYPE_BINARY and STRINGTYPE_BINARY0 was specified for <nType>. The strings are separated in memory by one 0-byte (two 0-bytes for Unicode strings) and the array is terminated by another 0-byte (two 0-bytes for Unicode strings) at the end. The memory allocated by LockStringArray must later on be explicitly released with ReleaseLockString. The string type recorded is always STRINGTYPE_BINARY. To read the data committed to memory use CopyMemoryToStringArray.
