Subject: [PATCH] distinguish XSI-compliant strerror_r from GNU-specifi
|
|
strerror_r
|
|
|
|
XSI-compliant strerror_r and GNU-specifi strerror_r are different.
|
|
|
|
int strerror_r(int errnum, char *buf, size_t buflen);
|
|
/* XSI-compliant */
|
|
|
|
char *strerror_r(int errnum, char *buf, size_t buflen);
|
|
/* GNU-specific */
|
|
|
|
We need to distinguish between them. Otherwise, we'll get an int value
|
|
assigned to (char *) variable, resulting in segment fault.
|
|
|
|
Upstream-Status: Inappropriate [musl specific]
