Scratch Buffer Functions. +More... + + + + + + + + + + + + + + + + + + +

Defines

+#define STP_BUF_LEN   8191
 Maximum size of buffer, not including terminating NULL.

Functions

void _stp_sprint (const char *fmt,...)
 Sprint into the scratch buffer.
+void _stp_sprint_str (const char *str)
void _stp_scbuf_clear (void)
 Clear the scratch buffer.

Variables

+char _stp_scbuf [8191+1]
 Scratch buffer for printing, building strings, etc.
+

Detailed Description

+Scratch Buffer Functions. +

+The scratch buffer is for collecting output before storing in a map, printing, etc. This is a per-cpu static buffer. It is necessary because of the limited stack space available in the kernel.

Function Documentation

+

+ + + + +
+ + + + + + + + + +
void _stp_scbuf_clear ( void   ) 
+
+ + + + + +
+   + + +

+Clear the scratch buffer. +

+Output from _stp_sprint() will accumulate in the buffer until this is called. +

+Definition at line 59 of file scbuf.c. +

+References _stp_scbuf, and STP_BUF_LEN.

+ + + + + + + + + + + + + + + + + + +
void _stp_sprint ( const char *  fmt,
  ...
) 
+
+ + + + + +
+   + + +

+Sprint into the scratch buffer. +

+Like printf, except output goes into _stp_scbuf, which will contain the null-terminated output. Safe because overflowing _stp_scbuf is not allowed. Size is limited by length of scratch buffer, STP_BUF_LEN.

+

Parameters:
+ + +
fmt A printf-style format string followed by a variable number of args.
