|KCGI_BUF_PUTS(3)||Library Functions Manual||KCGI_BUF_PUTS(3)|
put string content into a kcgi buffer
*buf, const char *cp);
Returns an enum kcgi_err indicating the error state.
- Success (not an error).
- Internal memory allocation failure.
- The output connection has been terminated. For FastCGI connections, the current connection should be released with khttp_free(3) and parse loop reentered.
- 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.
- Internal system error writing to the output stream.
The following creates a simple NUL-terminated buffer and outputs its contents. It does not perform any error checking.
struct kcgi_buf buf; memset(&buf, 0, sizeof(struct kcgi_buf)); kcgi_buf_puts(&buf, "Hello, world!"); puts(buf.buf); /* Emits "Hello, world!" */ free(buf.buf);
