21 The GDB/MI Interface
Function and purpose
GDB/MI is a line based machine oriented text interface to GDB. It is specifically intended
to support the development of systems which use the debugger as just one small
component of a larger system.
This chapter is a specification of the GDB/MI interface. It is written in the form of a
reference manual.
Notation and terminology
This chapter uses the following notation:
•
| separates two alternatives.
• [ something ] indicates that something is optional: it may or may not be given.
• ( group )* means that group inside the parentheses may repeat zero or more
times.
• ( group )+ means that group inside the parentheses may repeat one or more times.
• “string” means a literal string.
