execlp(2) OSS System Calls Reference Manual
STANDARDS CONFORMANCE
The POSIX standards leave some features to the implementing vendor to define. The following
features are affected in the HP implementation:
• Guardian attributes are associated with the new OSS process. See Guardian Attributes
under DESCRIPTION.
• [ENOENT] is returned in errno if the environment variable PATH is not defined when
the execlp() function is called.
• The contents of the st_atime field following a failed function call in which the file was
found should not be depended upon for further processing.
• The use of *env[]as a parameter in the call to main() is an HP extension.
The following are HP extensions to the XPG4 Version 2 specification:
• Text files containing the #! interpreter_name [optional_string] header line can execute.
• The [EINVAL], [ENODEV], [ENOTOSS], and [EUNKNOWN] error values are an HP
extension.
