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