From 18e43565574b700befc832ed4d25d25e40951f68 Mon Sep 17 00:00:00 2001 From: Laurent Bercot Date: Tue, 24 Nov 2020 21:45:56 +0000 Subject: Complete revamp of the pathexec functions - pathexec_run is now called exec_ae a for provided file name (default: argv[0]) e for provided envp (default: environ) - pathexec is now called mexec. m for merge environment. Option letters are: a for provided file name (default: argv[0]) e for provided envp (default: environ) f for provided envp *and* length of the envp m for provided modif string plus its length (the length is always needed because the modifs are null-terminated) n for provided modif string, length *and* number of modifs - functions have a foo0 version for _exit(0) when argv[0] is null - functions have a xfoo version to die if the exec fails - and a xfoo0 - Compatibility #defines and #includes are there until the next major bump --- src/libenvexec/env_string.c | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) create mode 100644 src/libenvexec/env_string.c (limited to 'src/libenvexec/env_string.c') diff --git a/src/libenvexec/env_string.c b/src/libenvexec/env_string.c new file mode 100644 index 0000000..e30f095 --- /dev/null +++ b/src/libenvexec/env_string.c @@ -0,0 +1,19 @@ +/* ISC license. */ + +#include +#include + +int env_string (stralloc *sa, char const *const *envp, size_t envlen) +{ + size_t salen = sa->len ; + size_t i = 0 ; + for (; i < envlen ; i++) + { + if (!stralloc_cats(sa, envp[i]) || !stralloc_0(sa)) + { + sa->len = salen ; + return 0 ; + } + } + return 1 ; +} -- cgit v1.2.3
