21.2.168. PMIx_Query_free

PMIx_Query_free — Release an array of pmix_query_t(5) structures and their contents.

21.2.168.1. SYNOPSIS

#include <pmix.h>

void PMIx_Query_free(pmix_query_t *p, size_t n);

21.2.168.1.1. Python Syntax

No Python equivalent

21.2.168.2. INPUT PARAMETERS

  • p: Pointer to the array of pmix_query_t(5) structures to be released.

  • n: Number of structures in the array.

21.2.168.3. DESCRIPTION

Release an array of pmix_query_t structures that was allocated by PMIx_Query_create(3). The function first destructs each of the n elements — freeing their keys and qualifiers contents, exactly as PMIx_Query_destruct(3) would — and then frees the storage of the array itself.

If p is NULL or n is zero, the function does nothing.

21.2.168.4. RETURN VALUE

PMIx_Query_free returns no value (void).

21.2.168.5. NOTES

The PMIX_QUERY_FREE convenience macro is a direct wrapper for this function; in addition to calling it, the macro sets the caller’s pointer to NULL.

Use PMIx_Query_free only on storage obtained from PMIx_Query_create(3). For a caller-provided (stack or embedded) structure, use PMIx_Query_destruct(3) instead, which releases the contents without freeing the structure storage.
