Initializing help system before first use

txtresize

Purpose
Resize and get a reference to the character buffer of a text object.
Synopsis
char *txtresize(XPRMctx ctx, void *sysctx, void *t, int s);
Arguments
ctx 
Mosel's execution context
sysctx 
Context of mmsystem
t 
Reference to a text object
s 
New size of the buffer (terminating 0 is not counted)
Return value
A reference to the new character buffer or NULL in case of memory error or if the provided text object is constant.
Further information
1. The buffer returned is terminated by the character 0 (like a C string) and can be modified as long as the size is not changed.
2. Since the memory management of the module may move text buffers when allocating memory, the pointer returned by this function is only valid until the next memory allocation.
