Initializing help system before first use

gettxtbuf

Purpose
Get a reference to the character buffer of a text object.
Synopsis
char *gettxtbuf(XPRMctx ctx, void *sysctx, void *t);
Arguments
ctx 
Mosel's execution context
sysctx 
Context of mmsystem
t 
Reference to a text object
Return value
A reference to the character buffer or NULL 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. If the length of the buffer has to be altered, use the function txtresize.
2. A NULL pointer will be returned if the provided text object is constant. Use getcsttxtbuf to retrieve the buffer of a constant text.
3. 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.
