2495 | This may all be followed by several keywords such as "if EXPR", | |

2500 | The function may be an undebuggable function found in minimal symbol table. | |

2504 | not OK to specify a variable or type to get its line number. | |
2505 | ||
2506 | DEFAULT_SYMTAB specifies the file to use if none is specified. | |
2507 | It defaults to current_source_symtab. | |
2508 | DEFAULT_LINE specifies the line number to use for relative | |
2509 | line numbers (that start with signs). Defaults to current_source_line. | |
2510 | If CANONICAL is non-NULL, store an array of strings containing the canonical | |
1777feb0 | 2511 | line specs there if necessary. Currently overloaded member functions and |
50641945 | 2512 | line numbers or static functions without a filename yield a canonical |
1777feb0 | 2513 | line spec. The array and the line spec strings are allocated on the heap, |
