.SH "Detailed Description"
.PP
Allows reading of values from configuration files This class allows a module to read from either the main configuration file (inspircd.conf) or from a module-specified configuration file.
It may either be instantiated with one parameter or none. Constructing the class using one parameter allows you to specify a path to your own configuration file, otherwise, inspircd.conf is read.

Dumps the list of errors in a config file to an output location. If bail is true, then the program will abort. If bail is false and user points to a valid user record, the error report will be spooled to the given user by means of NOTICE. if bool is false AND user is false, the error report will be spooled to all opers by means of a NOTICE to all opers.Definition at line 663 of file modules.cpp.

.SS "int ConfigReader::Enumerate (std::string tag)"
.PP
Counts the number of times a given tag appears in the config file. This method counts the number of times a tag appears in a config file, for use where there are several tags of the same kind, e.g. with opers and connect types. It can be used with the index value of \fBConfigReader::ReadValue\fP to loop through all copies of a multiple instance tag.Definition at line 696 of file modules.cpp.

Returns the number of items within a tag. For example if the tag was <test tag='blah' data='foo'> then this function would return 2. Spaces and newlines both qualify as valid seperators between values.Definition at line 701 of file modules.cpp.

.SS "long ConfigReader::GetError ()"
.PP
Returns the last error to occur. Valid errors can be found by looking in \fBmodules.h\fP. Any nonzero value indicates an error condition. A call to \fBGetError()\fP resets the error flag back to 0.Definition at line 656 of file modules.cpp.

.PP
Retrieves a boolean value from the config file. This method retrieves a boolean value from the config file. Where multiple copies of the tag exist in the config file, index indicates which of the values to retrieve. The values '1', 'yes' and 'true' in the config file count as true to ReadFlag, and any other value counts as false.Definition at line 610 of file modules.cpp.

Retrieves an integer value from the config file. This method retrieves an integer value from the config file. Where multiple copies of the tag exist in the config file, index indicates which of the values to retrieve. Any invalid integer values in the tag will cause the objects error value to be set, and any call to \fBGetError()\fP will return CONF_INVALID_NUMBER to be returned. needs_unsigned is set if the number must be unsigned. If a signed number is placed into a tag which is specified unsigned, 0 will be returned and \fBGetError()\fP will return CONF_NOT_UNSIGNEDDefinition at line 627 of file modules.cpp.
