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