Function Documentation

ggma_create_context()

GGMA_STATUS ggma_create_context	(	ggma_context **	context,
		const char *	package_path
	)

Creates a context from a package path.

This function initializes a context for inference from the specified package path. Once the context is no longer needed, it must be destroyed by calling ggma_free_context.

Parameters

[out]	context	A pointer to the variable that will receive the new context handle.
[in]	package_path	The path to the GGMA package directory.

Returns

GGMA_STATUS_NO_ERROR on success, or an appropriate error code on failure.

ggma_free_context()

GGMA_STATUS ggma_free_context

(

ggma_context *

context

)

Closes a GGMA context and releases its resources.

This function deallocates all resources associated with the context, including the GGMA package it was created with. After this function returns, the context handle is invalid and must not be used.

Parameters

[in]

context

The context to close.

Returns

GGMA_STATUS_NO_ERROR on success, or an appropriate error code on failure.
