putc - put a byte on a stream
#include <stdio.h>
int putc(int c, FILE *stream);
[CX] The functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements described here and the ISO C standard is unintentional. This volume of IEEE Std 1003.1-2001 defers to the ISO C standard.The putc() function shall be equivalent to fputc(), except that if it is implemented as a macro it may evaluate stream more than once, so the argument should never be an expression with side effects.
Refer to fputc().
Refer to fputc().
None.
Since it may be implemented as a macro, putc() may treat a stream argument with side effects incorrectly. In particular, putc(c,*f++) does not necessarily work correctly. Therefore, use of this function is not recommended in such situations; fputc() should be used instead.
None.
