NAME¶
ixp_errbuf, ixp_errstr, ixp_rerrstr, ixp_werrstr, ixp_vsnprint
SYNOPSIS¶
#include <ixp.h>
char *ixp_errbuf(void);
void ixp_errstr(char *buf, int nbuf);
void ixp_rerrstr(char *buf, int nbuf);
void ixp_werrstr(const char *fmt, ...);
int (*ixp_vsnprint)(char *buf, int nbuf, const char *fmt, va_list);
PARAMETERS¶
- buf
- The buffer to read and/or fill.
- nbuf
- The size of the buffer.
- fmt
- A format string with which to write the errstr.
- ...
- Arguments to fmt.
DESCRIPTION¶
These functions simulate Plan 9's errstr functionality. They replace errno in
libixp. Note that these functions are not internationalized.
ixp_errbuf(3) returns the errstr buffer for the current thread.
ixp_rerrstr(3) fills
buf with the data from the current thread's
error buffer, while
ixp_errstr(3) exchanges
buf's contents with
those of the current thread's error buffer.
ixp_werrstr(3) formats the
given format string,
fmt, via
ixp_vsnprint(3) and writes it to
the error buffer.
ixp_vsnprint(3) may be set to a function which will format its arguments
write the result to the
nbuf length buffer
buf(3). The default
value is
vsnprintf(3). The function must format '%s' as a
nul-terminated string and may not consume any arguments not indicated by a
%-prefixed format specifier, but may otherwise behave in any manner chosen by
the user.
