WebJan 5, 2011 · The standards do not specify the size in bytes, because the definition of the byte is up to the implementation, e.g. char is byte, but byte size ( CHAR_BIT macro) may be 16 bit. The actual size as defined by the implementation. This, as other answers have already pointed out, is dependent on the implementation: the compiler. http://andersk.mit.edu/gitweb/openssh.git/blobdiff/63284fbbb88cc0de8c33b78a2faa747f63783baa..27f6fddf96494aed14227aca924ac4f786e6d769:/bufaux.c
