[libvirt] [PATCH] virConfGetValueSSizeT: Fix build on 32 bits
This function tries to get a ssize_t value from a config file.
But before returning it, it checks whether the value would fit in
ssize_t and if not an error is printed out among with the range
for the ssize_t type. However, on some platforms SSIZE_MAX may
actually be a signed long type:
util/virconf.c: In function 'virConfGetValueSSizeT':
util/virconf.c:1268:9: error: format '%zd' expects argument of type 'signed
size_t', but argument 9 has type 'long int' [-Werror=format=]
virReportError(VIR_ERR_INTERNAL_ERROR,
^
$ grep -r SSIZE_MAX /usr/include/
/usr/include/bits/posix1_lim.h:#ifndef SSIZE_MAX
/usr/include/bits/posix1_lim.h:# define SSIZE_MAX LONG_MAX
