int OS_VSNPrintf( char *dst, size_t len, const char *fmt, va_list vlist );
dst | Storage destination buffer for output character string |
len | Storage destination buffer size for output character string |
fmt | Character string output format (character string format) |
vlist | Variable argument list |
Always returns the number of characters if the format character string was output properly. The termination character ( \0
) is not included in this number.
The output character string is written to dst
. If the output character string is less than len
, all of the character strings and termination character ( \0
) are written. If the output character string is greater than or equal to len
: If len is not 0, the termination character ( \0
) is written to dst[len - 1]
.(2) If len is 0, nothing is done with dst
.
This function returns the simplified version of the format character string.
This function operates identically to vsnprintf()
from MSL, but the following features cannot be used:
CodeWarrior extension Pascal character string (#
s) MSL AltiVec extensions (v
,vh
,vl
,hv
,lv
,@
) Floating Points (e
,E
,f
,g
,G
,a
,A
) Wide character string (wchar_t
) NOTE: The shift_JIS mutlibyte character string can be used.
This function is compiled with weak symbols. Therefore you can overwrite them with your own function definitions.
