kcgi_writer

NAME

kcgi_writer_puts — write into a writer

library “libkcgi”

#include <sys/types.h>
#include <stdarg.h>
#include <stdint.h>
#include <kcgi.h>

enum kcgi_err
kcgi_writer_puts(struct kcgi_writer *writer, const char *cp);

The kcgi_writer_puts() function writes the NUL-terminated string cp to a writer channel opened by kcgi_writer_get(3). This allows writing after kcgi_writer_disable(3), unlike khttp_write(3). kcgi_writer_puts() is backed by kcgi_writer_write(3).

Returns an enum kcgi_err indicating the error state.

KCGI_OK: Success (not an error).
KCGI_ENOMEM: Internal memory allocation failure.
KCGI_HUP: The output connection has been terminated. For FastCGI connections, the current connection should be released with khttp_free(3) and parse loop reentered.
KCGI_FORM: The connection is still expecting headers with khttp_head(3). Indicates that khttp_body(3) did not return with success or was not invoked. For FastCGI connections, the current connection should be released with khttp_free(3) and parse loop reentered.
KCGI_SYSTEM: Internal system error writing to the output stream.
