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