(v)spprintf

I just implemented spprintf and vpprintf. Both are nearly the same as (v)snprintf. The difference is that using vspprintf you usee a dynamically allocated buffer which *can* have a maximum length. To reduce runtime cost the functions reallocate in buffers of 1K. The old value of *pbuf is ignored and set NULL on initialisation failure. If during a call not enough memory could be allocated you will not be modified (maybe i add a parameter for that). The result is the length as with (v)snprintf. If *pbuf != NULL you have to call efree(*pbuf). extern int spprintf( char **pbuf, size_t max_len, const char *format, ...); extern int vspprintf(char **pbuf, size_t max_len, const char *format, va_list ap); Currentls i used it to fix a problem in ext/exif and to have error_logs allowing longer messages by ini setting. I searched through the code and found many calls to (v)snprintf includeing those using php_printf. As php_printf is a replacement for printf i suggest we implement that function using vspprintf, too. But i could not test yet. So here is the diff on that: cvs -z3 -q diff main.c (in directory S:\php4\main\) Index: main.c =================================================================== RCS file: /repository/php4/main/main.c,v retrieving revision 1.443 diff -u -r1.443 main.c

        but i think that god's got a sick sense of humor
        and when i die i expect to find him laughing.
