firestring_snprintf (3)

#include <firestring.h>

long firestring_snprintf(char * out, const size_t size, const char * const format, ...)

firestring_snprintf() writes a maximum of size bytes to out based on the formatting rules specified in format and the further arguments provided.

As snprintf(3) is not a ANSI C function, firestring_snprintf() is provided as a replacement for programs wishing to maintain ANSI C compliance. It acts much like snprintf(3), except that it only uses single-letter format tags, and only supports a subset of the common formats. Formats supported:

%s - char *

%d - int

%l - long

%u - unsigned int

%y - unsigned long

%g - signed long long

%o - unsigned long long

%f - double

%t - time_t (printed in ISO format)

%e - struct firestring_estr_t *

The %s type handles NULL values by displaying the string "(null)". All numeric types support zero padding through the standard %02d format.

Returns the number of bytes written to out not including the trailing nil.
