Top Forums Programming Why segmentation(coredump) in the following code in C? Post 302530484 by kumaran_5555 on Tuesday 14th of June 2011 06:20:51 AM

compile your program with -g option and then execute, gdb.

I think you have posted only the one function, the problem could be even at the callee side, how the return value is being used there.

So try gdb and let us know, what you see.

the gdb says that the segmentation fault occurred in strnlen() , strnlen(3) - Linux man page

Check for such functions.

Why does this example C code run and yet SHOULD either not compile or give a segmentation fault?

Apologies for any typos... Well guys, been researching 'goto' in C and they say that you can't 'goto' labels in another function as a segmentation fault will occur. However I have found a way to 'goto' a label in another function that is NOT main() using the asm() function. As you know I... (14 Replies)

DJVU2HOCR(1)							 djvu2hocr manual						      DJVU2HOCR(1)

NAME
djvu2hocr - DjVu to hOCR converter SYNOPSIS
djvu2hocr [option...] djvu-file djvu2hocr {--version | --help | -h} DESCRIPTION
djvu2hocr converts hidden text from a DjVu file to the hOCR[1] format. OPTIONS
Text segmentation options --word-segmentation=simple Use the same word segmentation as found in the DjVu file. This is the default. --word-segmentation=uax29 Use the Unicode Text Segmentation[2] algorithm to break lines into words, possibly fixing word segmentation found in the DjVu file. Other options --version Output version information and exit. -h, --help Display help and exit. PORTABILITY
djvu2hocr uses a custom extension to hOCR to retain characters which cannot be directly represented in an HTML/XML document. For example, control character BEL (^G, U+0007), is converted into the following HTML chunk: <span class="djvu_char" title="#x07"> </span> SEE ALSO
