Consider a call
RET = snprintf(BUF, SIZE, FMT, ...)
and let LEN be the number that would be written to BUF if SIZE were
sufficiently large (not counting the trailing null byte).
C99 requires that snprintf
(A) modifies at most the first SIZE bytes of BUF,
(B) writes a trailing null byte except when SIZE=0, and
(C) always returns LEN.
All known implementations (except some ancient buggy ones, e.g., for
64-bit Solaris 7 from Oct. 1998) satisfy (A). As long as LEN<SIZE
they all write a trailing null byte and return LEN.
Condition (C) is, however, violated for LEN>=SIZE by some older
implementations (SUSv2, glibc <= 2.0.6, etc.) and for Windows even
(B) is violated..
TeX Live does not require the full C99 semantics, but will need that
(1) there is always a trailing null byte, and
(2) for LEN>=SIZE the return value is either >=SIZE or <0, i.e.,
(unsigned)RET >= (unsigned)SIZE.
A violation of (2) is detected by configure (except when cross
compiling) and by a runtime check in the initialization routine
kpathsea_set_program_name.
A violation of (1) is handled here through static inline wrapper
functions. */
