| 3 | cxref \- a simple C routine referencing program |
| 4 | .SH SYNOPSIS |
| 5 | .B cxref |
| 6 | file ... |
| 7 | .SH DESCRIPTION |
| 8 | .I Cxref |
| 9 | is a simple shell script which uses |
| 10 | .IR grep (UCB) |
| 11 | and |
| 12 | .IR ex (UCB) |
| 13 | and |
| 14 | .IR sort (1) |
| 15 | to make a listing of the routines in the specified C program |
| 16 | files and the lines on which they are defined. |
| 17 | It is useful as a summary when prowling in a large program, |
| 18 | especially since |
| 19 | .I cref |
| 20 | has a habit of looping on large program input. |

| 25 | .SH BUGS |
| 26 | .I Cxref |
| 27 | assumes that routines begin in the first column of lines, |
| 28 | and that type names are given on different lines than the routine names. |
| 29 | If you have a program which is in a different format than this, |
| 30 | .I cxref |
| 31 | will fail miserably. |
| 32 | The operating system, |
| 33 | C compiler, |
| 34 | Pascal translator, |
| 35 | .I ex |
| 36 | editor, |
| 37 | etc. all work with |
| 38 | .I cxref. |
