Function Documentation

rdm_tfsGetOption()

RDM_RETCODE rdm_tfsGetOption ( RDM_TFS tfs,
const RDM_TCHAR_T * keyword,
RDM_TCHAR_T * optValue,
size_t bytesIn,
size_t * bytesOut
)

#include <rdmtfsapi.h>

Get a single TFS option into a string.

This function retrieves a single runtime TFS option into a string value. The keyword parameter accepts the key for the option to get. The options are inherited by the database and/or SQL handle derived from this TFS handle.

Options are defined using keys or properties. Every key has a name and a value, delimited by an equals sign (=). The key name appears to the left of the equals sign. Key names are not case-sensitive. Unless otherwise noted, values are not case-sensitive.

Key Value Description
timeout Specify default lock timeout in seconds.
time_zone Specify current time zone.
storage Specify database storage mode.
cache_size Specify cache size.
item_format Specify row storage form.
locale Specify database locale.
error_format Specify error message format.
durability Specify database transaction safety level.
pack_file_size Specify pack file maximum size.
db_size Specify the maximum database size allocation.
vacuum_percentage Specify the vacuum trigger level for pack files.
vacuum_write_chunk_size Specify the vacuum scan size for pack files.
vacuum_read_chunk_size Specify the vacuum write size for pack files.
idindex_flush_threshold_on_close Specify the threshold for flushing the ID-index when the last database user closes the database.
idindex_flush_threshold Specify the threshold for flushing the ID-index.
idindex_cache_size Specify the size of the ID-index cache in byte.
Return values
sOKAY Normal, successful return.
eINVOPTION Invalid option is specified.
eRANGE Numeric value out of range.

[in] keyword [in] single option keyword
[out] optValue [out] option value in string

rdm_tfsGetOptions()

RDM_RETCODE rdm_tfsGetOptions ( RDM_TFS tfs,
RDM_TCHAR_T * optString,
size_t bytesIn,
size_t * bytesOut
)

#include <rdmtfsapi.h>

Get TFS options.

The function returns a semicolon-delimited list of options in the pair of keyword and value for the options specified in keywords.

Keywords should be a list of option values. If keyword is NULL, the function returns the pairs for all available options. If keyword is an empty string, the function returns an empty string.

Options are defined using keys or properties. Every key has a name and a value, delimited by an equals sign (=). The key name appears to the left of the equals sign. Key names are not case-sensitive. Unless otherwise noted, values are not case-sensitive.
