DESCRIPTION

XmCvtXmStringToByteStream converts a compound string to a string of bytes representing the compound string in Byte Stream format. This routine is typically used by the source of a data transfer operation to produce a Byte Stream representation for transferring a compound string to a destination.

If prop_return is not NULL, this function creates a string of characters in Byte Stream format and returns it in prop_return. The function also returns the number of bytes in prop_return. If prop_return is NULL, the function does not return the Byte Stream format string, but it does calculate and return the number of bytes that would appear in the Byte Stream format string.

string

Specifies a compound string to be converted to Byte Stream format

prop_return

Specifies a pointer to a string in Byte Stream format that is created and returned by this function. If prop_return is NULL, no Byte Stream format string is returned. When a Byte Stream format string is returned, the function allocates space to hold it. The application is responsible for managing this allocated space. The application can recover the allocated space by calling XtFree.

RETURN

Returns the number of bytes in the Byte Stream representation (whether or not the Byte Stream representation is returned).
