C_iio_context_info_get_description(context)

Get a description of a discovered context.

Parameters

• context::Ptr{iio_context_info}: A pointer to an iio_context_info structure.

Returns

• A pointer to a static NULL-terminated string

libIIO documentation

C_iio_context_info_get_uri(context)

Get the URI of a discovered context.

Parameters

• context::Ptr{iio_context_info}: A pointer to an iio_context_info structure.

Returns

• A pointer to a static NULL-terminated string

libIIO documentation

C_iio_context_info_list_free(ptr_context)

Free a context info list.

Parameters

• ptr_context::Ptr{Ptr{iio_context_info}} : A pointer to a const struct iio_context_info * typed variable.

libIIO documentation

C_iio_create_scan_block(backend, flags)

Create a scan block.

Parameters

• backend::String: A NULL-terminated string containing the backend to use for scanning. If NULL, all the available backends are used.
• flags::UInt32 : Unused for now. Set to 0.

Returns

• On success, a pointer to a iio_scan_block structure
• On failure, NULL is returned and errno is set appropriately

Introduced in version 0.20.

libIIO documentation

C_iio_create_scan_context(backend, flags)

Create a scan context.

Parameters

• backend::String : A NULL-terminated string containing the backend(s) to use for scanning (example: pre version 0.20 : "local", "ip", or "usb"; post version 0.20 can handle multiple, including "local:usb:", "ip:usb:", "local:usb:ip:"). If NULL, all the available backends are used.
• flags::UInt32 : Unused for now. Set to 0.

Returns

• On success, a pointer to a iio_scan_context structure
• On failure, NULL is returned and errno is set appropriately

libIIO documentation

C_iio_scan_block_destroy(scan_block)

Destroy the given scan block.

Parameters

• block::Ptr{iio_scan_block} : A pointer to an iio_scan_block structure

NOTE

After that function, the iio_scan_block pointer shall be invalid.

Introduced in version 0.20.

libIIO documentation

C_iio_scan_block_get_info(scan_block, index)

Get the iio_context_info for a particular context.

Parameters

• scan_block::Ptr{iio_scan_block} : A pointer to an iio_scan_block structure
• index::UInt32 : The index corresponding to the context.

Returns

• On success, a pointer to the specified iio_context_info
• On failure, NULL is returned and errno is set appropriately

Introduced in version 0.20.

libIIO documentation

C_iio_scan_block_scan(scan_block)

Enumerate available contexts via scan block.

Parameters

• scan_block::Ptr{iio_scan_block} : A pointer to a iio_scan_block structure.

Returns

• On success, the number of contexts found.
• On failure, a negative error number.

Introduced in version 0.20.

libIIO documentation

C_iio_scan_context_destroy(scan_context)

Destroy the given scan context.

Parameters

• scan_context::Ptr{iio_scan_context} : A pointer to an iio_scan_context structure

NOTE

After that function, the iio_scan_context pointer shall be invalid.

libIIO documentation

C_iio_scan_context_get_info_list(scan_context, context_info)

Enumerate available contexts.

Parameters

• scan_context::Ptr{iio_scan_context} : A pointer to an iio_scan_context structure
• context_info::Ref{Ptr{Ptr{iio_context_info}}} : A pointer to a const struct iio_context_info ** typed variable. The pointed variable will be initialized on success.

Returns

• On success, the number of contexts found.
• On failure, a negative error number.
