Initializing help system before first use

# getcsttxtbuf

Purpose
Get a reference to the constant character buffer of a text object.
Synopsis
`const char *getcsttxtbuf(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.
Further information
1. The buffer returned is terminated by the character 0 (like a C string), and it must not be modified (even if the provided text object is not constant). The function gettxtbuf should be used instead when the buffer of a non-constant text has to be altered.
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.
