I searched for "EINTR" in all manual pages of my Fedora 21. I found a long list of functions (filename of manual pages). But I didn't check each manual page.

There are false positive. For example, "stat" is listed, but in fact EINTR is only mentionned in commented text (not visible using the "man" command): "SVr4 documents additional stat() error conditions EINTR, ...".

Another example of false positive with system:
"""
Early  drafts  required, or allowed, system() to return with errno set to
[EINTR] if it was interrupted with a signal. This error return was removed, and
a requirement that system() not return until the child has terminated was
added. This  means  that  if  a waitpid()  call  in  system() exits with errno
set to [EINTR], system() must reissue the waitpid().
"""

Shell command to search for all EINTR:
find /usr/share/man -name "*.gz"|xargs zgrep -H EINTR > EINTR.txt

Shell command to extract file names from the output:

sed 's!.*/!!g' EINTR.txt|sed 's!\.[0-9][a-z]\?m\?\.gz:.*!!g'|sort -u > EINTR_files.txt
