modulemd_module_stream_read_file ()

ModulemdModuleStream *
modulemd_module_stream_read_file (const gchar *path,
                                  const gchar *module_name,

                                  GError **error);

Create a ModulemdModuleStream object from a YAML file.

Parameters

path

The path to a YAML document containing a module stream definition.

[in]

module_name

An optional module name to override the document on disk. Mostly useful in cases where the name is being auto-detected from git.

[in][nullable]

module_stream

An optional module stream name to override the document on disk. Mostly useful in cases where the name is being auto-detected from git.

[in][nullable]

error

A GError that will return the reason for a failed read.

[out]

Returns

A newly-allocated ModulemdModuleStream object if the YAML file was valid and contained exactly one document: modulemd subdocument. NULL if the document fails validation or multiple documents are encountered and sets NULL appropriately. See ModulemdModuleIndex for functions to read in multiple-subdocument YAML.

Return an upgraded copy of this object. Does not modify the original.

Parameters

self

This ModulemdModuleStream.

[in]

mdversion

The metadata version to upgrade to. If zero, upgrades to the highest-supported version.

[in]

error
