SYNOPSIS

#include <event-parse.h>

int tep_strerror(struct tep_handle *tep, enum tep_errno errnum, char *buf, size_t buflen);

DESCRIPTION

The tep_strerror() function converts tep error number into a human readable string. The tep argument is trace event parser context. The errnum is a regular errno, defined in errno.h, or a tep error number. The string, describing this error number is copied in the buf argument. The buflen argument is the size of the buf.

It as a thread safe wrapper around strerror_r(). The library function has two different behaviors - POSIX and GNU specific. The tep_strerror() API always behaves as the POSIX version - the error string is copied in the user supplied buffer.

RETURN VALUE

The tep_strerror() function returns 0, if a valid errnum is passed and the string is copied into buf. If errnum is not a valid error number, -1 is returned and buf is not modified.
