This command loads additional debug information into the debugger.
Syntaxadd-symbol-file filename [offset] [-option] [-s section address]...
Where:
filenameSpecifies the image, shared library, or Operating System (OS) module.
Note
Shared library and OS modules depend on connections that support loading these types of files. This option pends the file until the library or OS module is loaded.
offsetSpecifies the offset that is added to all addresses within the image. If
offsetAn image is zero.
A shared library is the load address of the library. If the application has not currently loaded the specified library then the request is pended until the library is loaded and the offset can be determined.
optionControls how debug information is loaded:
readnowSpecifies loading all debug information immediately. This option uses more memory and is slower to load but it enables faster debugging.
demandloadSpecifies loading debug information when required by the debugger. This option enables a faster load and uses less memory but debugging might be slower. This is the default.
sSpecifies the relocation of symbols being loaded from a relocatable object file.
sectionSpecifies the name of a section in a relocatable file.
addressSpecifies the address of the section. This can be either an address or an expression that evaluates to an address.
You can use the info files command to display
information about the loaded files.
