Stdputcharint300

Stdputcharint300 is a name used for a character output function in some C-family libraries. It is designed to write a single character to the standard output stream and to indicate success or failure to the caller. The function is not part of the ISO C standard and is typically found only in specific projects, educational materials, or vendor-specific toolchains as an extension or variant of the conventional putchar.

Although there is no universal definition, stdputcharint300 is commonly described as receiving an int argument that represents a character code, which is then written to stdout. Semantics are generally aligned with the standard putchar: on success the function returns a nonnegative value related to the written character (often the same value passed in, or that character cast to int); on error it returns EOF. The exact return value conventions may vary by implementation, so consulting the accompanying documentation is advised.

The naming convention hints at a few design ideas. The std prefix suggests a standard-like API, putchar indicates output of a single character, and the 300 suffix may denote a version, variant, or configuration of the function within a particular codebase. In practice, stdputcharint300 may be implemented as an inline wrapper around putchar, a macro, or a small wrapper function that adds instrumentation or platform-specific behavior.

Usage considerations include portability and compatibility. Because stdputcharint300 is not part of the standard library, code relying on it is not portable across all compilers or environments. Developers should rely on standard functions like putchar or fputc for portable I/O, and treat stdputcharint300 as a specialized or project-local utility when it appears.
