Subject: [PATCH] Use generic errstr.go implementation on musl
|
||
|
|
|
||
|
|
glibc provides two version of strerror_r() depending on a feature test
|
||
|
|
macro. The first is the XSI-compliant version which returns an int, the
|
||
|
|
second is GNU-specific and returns a char pointer.
|
||
|
|
|
||
|
|
Similarity, gcc's libgo provides two implementations of Errstr() both of
|
||
|
|
which use strerror_r(). On Linux, it is assumed that the GNU-specific
|
||
|
|
strerror_r version is used. However, musl only provides the
|
||
|
|
XSI-compliant version of strerror_r. This patch enables the generic
|
||
|
|
Errstr() implementation which also uses the XSI-compliant version of
|
||
|
|
strerror_r.
