Function Documentation

void* xcalloc_f ( size_t  nmemb,
size_t  size,
const char *  file,
int  line 
)

calloc

Parameters
nmembnumber of members
sizesize of member
filefname location of use
lineline location of use
Returns
buffer

This function is invoked via macro xcalloc in which file and line are set automatically.

Definition at line 302 of file xmalloc.c.

References log_level, log_level_initialized, xcalloc_d, xmalloc_fatal(), yaz_log(), yaz_log_module_level(), and YLOG_FATAL.

void xfree_f ( void *  p,
const char *  file,
int  line 
)

free

Parameters
pstring to be freed (might be NULL)
filefname location of use
lineline location of use

This function is invoked via macro xfree in which file and line are set automatically.

Definition at line 341 of file xmalloc.c.

References log_level, xfree_d, and yaz_log().

void* xmalloc_f ( size_t  size,
const char *  file,
int  line 
)

malloc

Parameters
sizesize of buffer to be allocated
filefname location of use
lineline location of use
Returns
buffer

This function is invoked via macro xmalloc in which file and line are set automatically.

References MALLOC_SIZE_MAX.

Referenced by xcalloc_f(), xmalloc_f(), and xrealloc_f().

void xmalloc_trav_f ( const char *  s,
const char *  file,
int  line 
)

logs all xmalloc buffers

Parameters
snot used
filefname location of use
lineline location of use

This function is invoked via macro xmalloc_trav in which file and line are set automatically. Only if TRACE_XMALLOC > 1 this function does any real work!

void* xrealloc_f ( void *  o,
size_t  size,
const char *  file,
int  line 
)

realloc

Parameters
obuffer to be reallocated
sizesize of buffer to be allocated
filefname location of use
lineline location of use
Returns
buffer

This function is invoked via macro xrealloc in which file and line are set automatically.

char* xstrdup_f ( const char *  p,
const char *  file,
int  line 
)

strdup

Parameters
pstring to be cloned
filefname location of use
lineline location of use
Returns
resulting string

This function is invoked via macro xstrdup in which file and line are set automatically.

)

strndup

Parameters
pstring to be cloned
nmax size of resulting string (excluding 0)
filefname location of use
lineline location of use
Returns
resulting string

This function is invoked via macro xstrndup in which file and line are set automatically.
