- get error message string
#include <string.h> char *strerror(int errnum);
int strerror_r(int errnum, char *strerrbuf, size_t buflen);
The strerror() function maps the error number in errnum to an error message string, and returns a pointer to that string. It uses the same set of error messages as perror(3C). The returned string should not be overwritten.
The strerror_r() function maps the error number in errnum to an error message string and returns the string in the buffer pointed to by strerrbuf with length buflen.
Upon successful completion, strerror() returns a pointer to the generated message string. Otherwise, it sets errno and returns a pointer to an error message string. It returns the string “Unknown error” if errnum is not a valid error number.
Upon successful completion, strerror_r() returns 0. Otherwise it sets errno and returns the value of errno to indicate the error. It returns the string “Unknown error” in the buffer pointed to by strerrbuf if errnum is not a valid error number.
These functions may fail if:
The value of errnum is not a valid error number.
The strerror_r() function may fail if:
The buflen argument specifies insufficient storage to contain the generated message string.
Messages returned from these functions are in the native language specified by the LC_MESSAGES locale category. See setlocale(3C).
