But plugins use auxalloc(), which afaict is not in the
API proper. Also ftfind() and ftnp2find() are not there.
These are actual opcode API functions, in my view.

Plugins can probably use these functions for those operations:

/**
   * Returns the length of a function table, or -1 if the table does
   * not exist.
   */
  PUBLIC int csoundTableLength(void *csound, int table);

  /**
   * Returns the value of a slot in a function table.
   */
  PUBLIC MYFLT csoundTableGet(void *csound, int table, int index);

  /**
   * Sets the value of a slot in a function table.
   */
  PUBLIC void csoundTableSet(void *csound, int table, int index, MYFLT value);

/**
   * Allocate nbytes bytes of memory that can be accessed later by calling
   * csoundQueryGlobalVariable() with the specified name; the space is
   * cleared to zero.
   * Returns CSOUND_SUCCESS on success, CSOUND_ERROR in case of invalid
   * parameters (zero nbytes, invalid or already used name), or
   * CSOUND_MEMORY if there is not enough memory.
   */
  PUBLIC int csoundCreateGlobalVariable(void *csound, const char *name,
                                        size_t nbytes);

  /**
   * Get pointer to space allocated with the name "name".
   * Returns NULL if the specified name is not defined.
   */
  PUBLIC void *csoundQueryGlobalVariable(void *csound, const char *name);

  /**
   * This function is the same as csoundQueryGlobalVariable(), except the
   * variable is assumed to exist and no error checking is done.
   * Faster, but may crash or return an invalid pointer if 'name' is
   * not defined.
   */
  PUBLIC void *csoundQueryGlobalVariableNoCheck(void *csound, const char *name);

  /**
   * Free memory allocated for "name" and remove "name" from the database.
   * Return value is CSOUND_SUCCESS on success, or CSOUND_ERROR if the name is
   * not defined.
   */
  PUBLIC int csoundDestroyGlobalVariable(void *csound, const char *name);

These still not include auxalloc which is frequently used for things
like delay lines etc. The csound5 API does include auxalloc (actually,
with the name auxalloc_, but I assume these ugly underscored names
are only for compatibility with the - even uglier - macros, and thus
may eventually be replaced).
It is interesting that the table functions do not include one that
returns a MYFLT* pointer to the table data.
