| const struct sr_transform_module** sr_transform_list | ( | void | ) |
Returns a NULL-terminated list of all available transform modules.

| const struct sr_transform* sr_transform_new | ( | const struct sr_transform_module * | tmod, |
| GHashTable * | options, | ||
| const struct sr_dev_inst * | sdi | ||
| ) |
Create a new transform instance using the specified transform module.
options is a *GHashTable with the keys corresponding with the module options' id field. The values should be GVariant pointers with sunk * references, of the same GVariantType as the option's default value.
The sr_dev_inst passed in can be used by the instance to determine channel names, samplerate, and so on.

| const struct sr_option** sr_transform_options_get | ( | const struct sr_transform_module * | tmod | ) |
Returns a NULL-terminated array of struct sr_option, or NULL if the module takes no options.
Each call to this function must be followed by a call to sr_transform_options_free().
