The documented prototype for mlock2() was a mix of the
glibc wrapper prototype and the kernel syscall prototype.
Let's document the glibc wrapper prototype, which is shown below.
......
.../glibc$ grep_glibc_prototype mlock2
sysdeps/unix/sysv/linux/bits/mman-shared.h:55:
int mlock2 (const void *__addr, size_t __length, unsigned int __flags) __THROW;
.../glibc$
function grep_glibc_prototype()
{
if ! [ -v 1 ]; then
>&2 echo "Usage: ${FUNCNAME[0]} <func>";
return ${EX_USAGE};
fi
find * -type f \
|grep '\.h$' \
|sort -V \
|xargs pcregrep -Mn \
"(?s)^[^\s#][\w\s]+\s+\**${1}\s*\([\w\s()[\]*,]*?(...)?\)[\w\s()]*;" \
|sed -E 's/^[^:]+:[0-9]+:/&\n/';
