250 | .TH H2PH 1 "August 8, 1990" |
251 | .AT 3 |
252 | .SH NAME |
253 | h2ph \- convert .h C header files to .ph Perl header files |
254 | .SH SYNOPSIS |
255 | .B h2ph [headerfiles] |
256 | .SH DESCRIPTION |
257 | .I h2ph |
258 | converts any C header files specified to the corresponding Perl header file |
259 | format. |
260 | It is most easily run while in /usr/include: |
261 | .nf |
262 | |
263 | cd /usr/include; h2ph * sys/* |
264 | |
265 | .fi |
fe14fcc3 |
266 | If run with no arguments, filters standard input to standard output. |
154e51a4 |
267 | .SH ENVIRONMENT |
268 | No environment variables are used. |
269 | .SH FILES |
270 | /usr/include/*.h |
271 | .br |
272 | /usr/include/sys/*.h |
273 | .br |
274 | etc. |
275 | .SH AUTHOR |
276 | Larry Wall |
277 | .SH "SEE ALSO" |
278 | perl(1) |
279 | .SH DIAGNOSTICS |
280 | The usual warnings if it can't read or write the files involved. |
281 | .SH BUGS |
282 | Doesn't construct the %sizeof array for you. |
283 | .PP |
284 | It doesn't handle all C constructs, but it does attempt to isolate |
285 | definitions inside evals so that you can get at the definitions |
286 | that it can translate. |
287 | .PP |
288 | It's only intended as a rough tool. |
289 | You may need to dicker with the files produced. |
