#define IOLIBDIR_ENV "IOLIBS" |
IOLIBDIR_ENV:
Name of the environment variable which may contain the path where to look for the IO libs. If this environment variable is not defined, use the compiled-in default constant.

int gp_port_info_list_append | ( | GPPortInfoList * | list, |
GPPortInfo | info | ||
) |
Append a portinfo to the port information list.
list | a #GPPortInfoList |
info | the info to append |
Appends an entry to the list. This function is typically called by an io-driver during #gp_port_library_list. If you leave info.name blank, gp_port_info_list_lookup_path will try to match non-existent paths against info.path and - if successfull - will append this entry to the list.

int gp_port_info_list_count | ( | GPPortInfoList * | list | ) |
Number of ports in the list.
list | a #GPPortInfoList |
Returns the number of entries in the passed list.
References gp_log(), GP_LOG_DEBUG, and _GPPortInfo::name.
Referenced by gp_abilities_list_detect().
int gp_port_info_list_free | ( | GPPortInfoList * | list | ) |
Free a GPPortInfo list.
list | a #GPPortInfoList |
Frees a GPPortInfoList structure and its internal data structures.
References GP_OK.

int gp_port_info_list_get_info | ( | GPPortInfoList * | list, |
int | n, | ||
GPPortInfo * | info | ||
) |
Get port information of specific entry.
list | a #GPPortInfoList |
n | the index of the entry |
info | the returned information |
Retreives an entry from the list and stores it into info.

int gp_port_info_list_load | ( | GPPortInfoList * | list | ) |
Load system ports.
list | a #GPPortInfoList |
Searches the system for io-drivers and appends them to the list. You would normally call this function once after gp_port_info_list_new and then use this list in order to supply gp_port_set_info with parameters or to do autodetection.

int gp_port_info_list_lookup_name | ( | GPPortInfoList * | list, |
const char * | name | ||
) |
Look up a name in the list.
list | a #GPPortInfoList |
name | a name |
Looks for an entry in the list with the exact given name.
References GP_ERROR_UNKNOWN_PORT, gp_log(), GP_LOG_DEBUG, and _GPPortInfo::name.
int gp_port_info_list_lookup_path | ( | GPPortInfoList * | list, |
const char * | path | ||
) |
Lookup a specific path in the list.
list | a #GPPortInfoList |
path | a path |
Looks for an entry in the list with the supplied path. If no exact match can be found, a regex search will be performed in the hope some driver claimed ports like "serial:*".

int gp_port_info_list_new | ( | GPPortInfoList ** | list | ) |
Create a new GPPortInfoList.
list | pointer to a GPPortInfoList* which is allocated |
Creates a new list which can later be filled with port infos (GPPortInfo) using gp_port_info_list_load.
References GP_ERROR_NO_MEMORY, and GP_OK.

const char* gp_port_message_codeset | ( | const char * | codeset | ) |
Specify codeset for translations.
This function specifies the codeset that are used for the translated strings that are passed back by the libgphoto2_port functions.
This function is called by the gp_message_codeset() function, there is no need to call it yourself.
