If you want something like the information printed by the "-z1" command
line option, then the functions below are probably what you are looking
for. Currrently, csoundNewOpcodeList() should be called after
csoundCompile(); this means that you may need to compile a temporary
"dummy" orchestra first; it should be enough if it only contains
"instr 1\nendin\n", a score is not needed, and sound output can also
be disabled with the "-n" flag. The limitation of having to compile
something first before creating an opcode list may be removed in a
future version, however.

By the way, entry1.h does not contain the opcode list, and even in
entry1.c you will only find the opcodes built into the Csound API
library, but not the plugins.

  typedef struct {
    char        *opname;
    char        *outypes;
    char        *intypes;
  } opcodeListEntry;

  /**
   * Gets an alphabetically sorted list of all opcodes.
   * Should be called after externals are loaded by csoundCompile().
   * Returns the number of opcodes, or a negative error code on failure.
   * Make sure to call csoundDisposeOpcodeList() when done with the list.
   */
  PUBLIC int csoundNewOpcodeList(CSOUND *, opcodeListEntry **opcodelist);

  /**
   * Releases an opcode list.
   */
  PUBLIC void csoundDisposeOpcodeList(CSOUND *, opcodeListEntry *opcodelist);
