[PATCH] clibpdf -- get_buffer_length()

Patch that allows retrieval of the length in bytes of the output buffer for a finalized pdf document that has been created in memory. This is good for sending a 'Content-Length' header before outputting the pdf file from memory. MSIE requires a properly set 'Content-Length' header in order to display the pdf document correctly. -- Justin Garrett ----------START PATCH-------------------------------- /* {{{ proto int cpdf_buffer_length(int pdfdoc) Returns current length of the output buffer */ PHP_FUNCTION(cpdf_buffer_length) { pval *arg1; int id, type, length; CPDFdoc *pdf; CPDF_TLS_VARS; if (ZEND_NUM_ARGS() != 1 || getParameters(ht, 1, &arg1) == FAILURE) { WRONG_PARAM_COUNT; } convert_to_long(arg1); id=arg1->value.lval; pdf = zend_list_find(id,&type); if(!pdf || type!=CPDF_GLOBAL(le_cpdf)) { php_error(E_WARNING,"Unable to find identifier %d",id); RETURN_FALSE; } cpdf_getBufferForPDF(pdf, &length); RETURN_LONG(length); } /* }}} */ --------END PATCH-----------------------------------
