The following functions are declared in the skalibs/lolstdio.h header, and implemented in the libskarnet.a or libskarnet.so library.
lolstdio is a set of convenience functions providing printf-style formatting but interacting with buffers or bufallocs instead of stdio FILEs.
Like any printf-style functions, the lolstdio functions are rather complex and inefficient, and not recommended for general use; they are provided as a quick and dirty way to debug or test things. Programmers are advised to use type-specific formatting functions instead in production-quality code.
Be aware that functions writing into buffers interact badly with non-blocking fds (and asynchronism in general) - just as you cannot use FILEs with non-blocking output. Functions writing into bufallocs, however, are fine, because bufallocs are much more suited to asynchronous writing than fixed-size buffers or FILEs are.
The current lolstdio implementation relies on the libc's vsnprintf function.
int vbprintf (buffer *b, char const *format, va_list args)
Like vfprintf
except that the result is written to the buffer b.
int bprintf (buffer *b, char const *format, ...)
Like fprintf
except that the result is written to the buffer b.
int lolprintf (char const *format, ...)
Like printf
except that the result is written to the buffer buffer_1.
int vbaprintf (bufalloc *ba, char const *format, va_list args)
Like vfprintf
except that the result is written to the bufalloc ba.
int baprintf (bufalloc *ba, char const *format, ...)
Like fprintf
except that the result is written to the bufalloc ba.
