- exacct catalog tag manipulation
use Sun::Solaris::Exacct::Catalog qw(:ALL); my $ea_cat = Sun::Solaris::Exacct::Catalog->new( &EXT_UINT64 | &EXC_DEFAULT | &EXD_PROC_PID);
This class provides a wrapper around the 32-bit integer used as a catalog tag. The catalog tag is represented as a Perl object blessed into the Sun::Solaris::Exacct::Catalog class so that methods can be used to manipulate fields in a catalog tag.
All the EXT_*, EXC_*, and EXD_* macros are provided as constants. Constants passed to the methods below can either be the integer value such as EXT_UINT8 or the string representation such as "EXT_UINT8".
This method is used to register application-defined libexacct(3LIB) catalogs with the exacct Perl library. See </usr/include/sys/exacct_catalog.h> for details of the catalog tag format. This method allows symbolic names and strings to be used for manipulating application-defined catalogs. The first two parameters define the catalog prefix and associated numeric catalog ID. If the $export parameter is true, the constants are exported into the caller's package. The final parameter is a list of (id, name) pairs that identify the required constants. The constants created by this method are formed by appending $cat_pfx and "_" to each name in the list, replacing any spaces with underscore characters and converting the resulting string to uppercase characters. The $catalog_name value is also created as a constant by prefixing it with EXC_ and converting it to uppercase characters. Its value becomes that of $catalog_id shifted left by 24 bits. For example, the following call:
Sun::Solaris::Exacct::Catalog->ea_register("MYCAT", 0x01, 1, FIRST => 0x00000001, SECOND => 0x00000010);
results in the definition of the following constants:
EXC_MYCAT 0x01 << 24 MYCAT_FIRST 0x00000001 MYCAT_SECOND 0x00000010
Only the catalog ID value of 0x01 is available for application use (EXC_LOCAL). All other values are reserved. While it is possible to use values other than 0x01, they might conflict with future extensions to the libexacct file format.
If any errors are detected during this method, a string is returned containing the appropriate error message. If the call is sucessful, undef is returned.
This method creates and returns a new Catalog object, which is a wrapper around a 32-bit integer catalog tag. Three possible argument lists can be given. The first variant is to pass an integer formed by bitwise-inclusive OR of the appropriate EX[TCD]_* constants. The second variant is to pass an existing Catalog object that will be copied. The final variant is to pass in the type, catalog and ID fields as separate values. Each of these values can be either an appropriate integer constant or the string representation of the constant.
This method allows the value of the catalog tag to be queried. In a scalar context it returns the 32-bit integer representing the tag. In a list context it returns a (type, catalog, id) triplet, where each member of the triplet is a dual-typed scalar.
This method returns the type field of the catalog tag as a dual-typed scalar.
This method returns the catalog field of the catalog tag as a dual-typed scalar.
This method returns the id field of the catalog tag as a dual-typed scalar.
These methods return string representations of the appropriate value. These methods can be used for textual output of the various catalog fields. The string representations of the constants are formed by removing the EXT_, EXC_, or EXD_ prefix, replacing any underscore characters with spaces, and converting the remaining string to lowercase characters.
By default nothing is exported from this module. The following tags can be used to selectively import constants and functions defined in this module:
EXT_*, EXC_*, and EXD_*
