NAME¶
fmt_netstring - convert a memory buffer into a netstring
SYNTAX¶
#include <libowfat/fmt.h>
size_t fmt_netstring(char *dest,const char
*source,
size_t len);
DESCRIPTION¶
fmt_netstring creates a netstring from a raw memory buffer and returns the length.
fmt_netstring does not append \0.
If dest equals FMT_LEN (i.e. is zero), fmt_netstring returns the number of bytes it would have written.
RETURN VALUE¶
fmt_netstring returns the number of bytes written (or that would have been written, had the destination pointer not pointed to NULL).
If the input buffer is implausibly large, fmt_netstring returns 0 instead.
EXAMPLE¶
The raw memory buffer "foo" would become the netstring "3:foo,"
