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¶
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.
