then why does glibc look accepting -std=c99 -D_POSIX_C_SOURCE=200809L?
so you mean linux (maybe glibc?) is wrong and cygwin (maybe newlib?) is right?
w/ attached source that uses popen()/pclose() via gcc -std=c99,
on cygwin (maybe newlib?), i got,
p.c: In function ‘main’:
p.c:5:2: warning: implicit declaration of function ‘popen’
[-Wimplicit-function-declaration]
FILE *pp = popen("cat", "w");
^
p.c:5:13: warning: initialization makes pointer from integer without a cast
FILE *pp = popen("cat", "w");
^
p.c:12:3: warning: implicit declaration of function ‘pclose’
[-Wimplicit-function-declaration]
int err = pclose(pp);
^
on linux (maybe glibc?), i got,
p.c: In function 'main':
p.c:4:14: warning: unused parameter 'argc' [-Wunused-parameter]
int main(int argc, char *argv[]) {
^
p.c:4:26: warning: unused parameter 'argv' [-Wunused-parameter]
int main(int argc, char *argv[]) {
^ ^
Peace,
