cscope is an interactive program that locates specified elements of code in C, lex, or yacc source files. With cscope, you can search and edit your source files more efficiently than you could with a typical editor. That’s because cscope supports function calls—when a function is being called, when it is doing the calling—as well as C language identifiers and keywords.
This chapter is a tutorial on the cscope browser provided with this release.
Note - The cscope program has not yet been updated to understand codes written for the 1999 ISO/IEC C standard. For example, it does not yet recognize the new keywords introduced in the 1999 ISO/IEC C standard.
